Specifically thinking of stuff that make your life better in the long run but all kinds of answers are welcome!
I’ve recently learnt about lifetraps and it’s made a huge positive impact on how I view myself and my relationships
- Exercise grows your hippocampus
- So do antidepressants according to recent research
- Small hippocampal volume is an excellent predictor of depression and anxiety
- Exercise grows your hippocampus, in a dose-dependent way
- Exercise grows your hippocampus
- Exercise grows your hippocampus
This is the most important fact I have ever learned.
But is there any benefit to exercise?
Not sure, it wasn't very clear from the comment.
Just adding some sauce for the weird cult like talk: https://www.pnas.org/doi/10.1073/pnas.1015950108
Excuse me what do you think is cult like about that?
It straight up reads like cult craziness or crazy 2 am infomercials. HEAD ON! APPLY DIRECTLY TO FOREHEAD! I'm glad you've placebo'd yourself into happiness though lol.
You said Exercise grows your hippocampus in 4 different bullet points lmfao. Great, it increases size by 2%. It proves nothing about whether it affects depression in adults. In fact, the studies show they do jack shit except help memory lol.
Exercise training increased hippocampal volume by 2%, effectively reversing age-related loss in volume by 1 to 2 y.
More showing it means little to nothing:

The effect of aerobic exercise on hippocampal volume in patients with psychotic disorders
Four studies examined the effect of aerobic exercise on hippocampal volume in people with schizophrenia or first episode psychosis (n = 107). Aerobic exercise did not significantly increase total hippocampal volume compared to control conditions (g = 0.149, 95% CI: -0.31 to 0.60, p = 0.53, Table 2). Among the two studies which reported effects on left/right hippocampus separately, there was no evidence of effects in either region (both p > 0.1). There was also no evidence of heterogeneity or publication bias influencing these results.
The effect of aerobic exercise on hippocampal volume in other populations
Data in other populations was insufficient for pooled meta-analyses, and so results from individual trials are summarised below. Individual trials which examined effects of aerobic exercise in patients with depression (Krogh et al., 2014), mild cognitive impairment (Brinke et al., 2014) and probable Alzheimer's disease (Morris et al., 2017) all found no significant effects on total or left/right hippocampal volumes. One study examining the effects of exercise in young-to-middle-aged adults found no change in total hippocampal volume but did find a significant increase in anterior hippocampal volume following 6 weeks of aerobic exercise (Thomas et al., 2016).
Effects of exercise in relation to participant age
Meta-regression analyses were performed to examine the relationship between mean sample age and effects of exercise on hippocampal volume. No statistically significant associations of effects of exercise with sample age were found for total, right or left hippocampal volume (all p > 0.05).
In conclusion, this meta-analysis found no effects of exercise on total hippocampal volume, but did find that exercise interventions retained left hippocampal volume significantly more than control conditions. As these positive effects were also observed among the subgroup of studies of healthy older adults, the findings hold promising implications for using exercise to attenuate age-related neurological decline. Currently, the overall quality of the evidence is compromised by the fact that 10 of the 12 studies included some risk of bias, therefore more high-quality RCTs are now required. In additional to RCTs, a prospective meta-analysis examining how changes in physical activity and fitness predict hippocampal retention/deterioration across the lifespan would provide novel insights into longer-term neural effects of exercise, while also reducing the impact of methodological heterogeneity often found across exercise RCTs. Further research is also required to determine effects in younger people (Riggs et al., 2016), and establish the neurobiological mechanisms through which exercise exerts these effects, in order to design optimal exercise programs for producing neurocognitive enhancements. However, the functional relevance of structural improvements has also yet to be ascertained. Nonetheless, the link between cardiorespiratory fitness with both structural and performance increases indicates this as a suitable target for aerobic training programs to improve brain health.
So it’s right there in the results you quoted:
In conclusion, this meta-analysis found no effects of exercise on total hippocampal volume, but did find that exercise interventions retained left hippocampal volume significantly more than control conditions.
Apparently it simultaneously shrinks your right hippocampus while growing your left, for an average change of zero while the left grows?
That’s the only way that sentence makes sense.
I read that as “the hippocampus shrinks at a rate of [x] [y]s per [z]. Exercise slows that shrinking in the left hippocampus.”
Agreed.
I wonder if it would “regenerate” an atrophied or shrunken hippocampus. Like the way rest and nutrition won’t make your skin larger but it will heal missing patches of skin.
I know I’ve seen claims from reputable sources that exercise raised BDNF levels, and that BDNF leads to hippocampal neurogenesis. I can find the sources again I’m sure if you’d like; let me know.
But how could hippocampal neurogenesis be happening without volume change? Could it be replacing dead cells (and preventing shrinkage)? Packing neurons in more densely?
Okay so it’s not making anything grow. Yeah that’s probably it.
Though that is still an effect on hippocampal volume.
Maybe they meant to say something like:
“Overall exercise doesn’t affect hippocampal volume, except in cases the hippocampus is actively shrinking in which case it can slow down the left side” (and reading between the lines possibly on the right side with a p value a little higher than significant?)
Oh you noticed the repetition did you?
So hang on. Are you trying to tell me that exercise grows the hippocampus?
What do you mean by "in a dose dependent way"?
I think it means more exercise leads to more growth.
So does meditation according to my psychiatrist
Apparently it also increases the feeling of needing to repeat yourself 🤔
You can only help people who want to be helped. That goes for yourself, too. You can't help yourself until you actually have the desire to improve.
In the same vein, wanting different outcomes requires different incomes.
Take all your actions and add them up = this. If you wanted that not this, all your inputs need to be under the spotlight and changes made; including and especially habits, vices, behaviours, opinions, assumptions, collection and quality of knowledge, relationships, etc etc. Sometimes the cost or sacrifice from and of yr current self is large and largely invisible.
Being uncomfortable means you're learning. Learning means you're growing. If you're never uncomfortable, you haven't reached luxury and made it, you've reached stagnation and have stopped 'living' your life.
Choosing the lesser of two evils, or the devil you know, or never doing anything about a life you don't like or want, is cowardice and will slowly crush your soul into despair. Choosing the unknown might end up sucking, but it might be better. If the known is guaranteed to suck, take the unknown - at least there's hope there and despair, a feeling worse than pain, is a failing to find hope.
Pretty awesome advice!
This is true. But if it's somebody important your life, social pressure can help.
Demonstrate the lifestyle you want to help them lead. Give them opportunities to join you, not pushy opportunities just let's do a thing together. And you demonstrate the better lifestyle.
No it wouldn't get somebody off drugs. But it might help somebody exercise more or eat healthier if you normalize it
Drowning is very fast, seconds not minutes like in the movies. People in distress can take minutes before they are actively drowning. Active drowning is silent, they will not be yelling for help. It looks like the person is "climbing" or pushing down at the water. They will be vertical in the water and may be "bobbing", going underwater and resurfacing. They will have their head tilted back parallel to the surface of the water.
If you see someone go under in open water keep looking at where they went under while calling for help, don't take your eyes off it. If you are the only one who saw them go under, your job is to direct others to where they went down. In open water it's very hard to find people because the bottom isn't visible.
Username does not check out.
Also drowning can happen after inhalation of water. All incidents involving children being rescued from water may require medical intervention, even if they seem fine initially. "Dry drowning"
If you see someone go overboard, get someone else to start throwing stuff off the deck to where they are in the water (while you keep pointing at them). Makes for much easier locating by others, and a quicker rescue
We trained on this a lot. Also yelling "swim" because apparently the shock of sudden cold water can make you forget to do that.
There's a YouTube channel that shows videos of people drowning and being rescued so you can see what it looks like: https://youtube.com/@LifeguardRescue
Here is an alternative Piped link(s):

This is true regardless of symptom severity or health status, every person is at risk. I think most people really aren't aware of this, they absorbed the narrative that it's gone, mild, only kills/harms the vulnerable, etc. This isn't really their fault, there are a lot of factors that have led people to that belief, but people should know their lives and livelihoods are much more at risk now than 4 years ago.
And that this isn't inevitable, there are simple methods of disrupting transmission and protecting yourself and others. COVID-19 is here to stay (unless we do something about that) and it has impacts on every person infected and on society at large. That shouldn't mean folks accept illness and worse quality of life. We adapt and adopt precautions in our life to reduce long-term health impacts, like we've done before with many other illnesses that plague humanity.
And the possible risks are compounded with each infection. People are acting like covid just isn't a problem anymore, like it's gone away. Meanwhile, roughly 100 Americans are dying of covid every day - and we're not even in a surge at the moment.
I'm too lazy to verify your numbers, but realistically, covid nowadays is simply just another life risk. Yes, people are still dying and that's bad, but most of them are just in the age where people tend to die of such infections.
I'd guess, there are about 4 million deaths a year in a country the size of the US. So having something on the order of 100k per year due to covid isn't that concerning, if the lifespan isn't affected that much.
We have vaccinations against covid. If you're properly vaccinated, you'll probably be fine and younger children will grow up in a world where you just get covid once in a while and get better immunity than we old folks could ever have.
Get this though: many children still do end up hospitalized. The majority of them have no underlying comorbidities or conditions. Their only reason for ending up in hospital is luck of the draw. That was presented at the CDC meeting where the recent booster was approved. It's not just the elderly or infirm who end up in the hospital and die from it. It's still killing, hospitalizing, and making seriously ill way more people than flu.
Yes, but as I said: this is just life now.
You're getting all raved up about covid, but in reality, this is just a tiny bit more risk. Yes, more risk is bad, but what is the alternative? Continuous shutdown forever?
You have to accept, that there are just some risks that we have to accept. If you're going out on the street, there's a chance you'll be run over, do you stay indoors all the time because of that?
No, we don't have to just accept continuous illness and death. Why do you think that it's necessary for people to suffer when there are simple solutions? There are steps between nothing and total shutdown, read above for some of them.
Covid isn't like people going in the street risking getting hit. Covid is a communicable illness spread by others, not a personal choice someone makes. People can't just choose to never be exposed even if they wanted, we have to interact with others. Further, people can and do avoid being run over in the street by walking on sidewalks and crosswalks, riding in vehicles with protections, with lots of traffic safety rules in place to minimize accidents. Right now our covid elimination strategies are similar to that of traffic safety in the early days of automobiles when there were no safety regulations. Right now we have a bunch of people driving wildly with at best ineffective vaccines, we need a lot more than that if we want to stop repeatedly trying to dodge covid crashes and have any sense of stability in actually living with covid.
There are no simple solutions. Vaccines solve 95% of the problem, but not 100%, and the remaining 5% are what you're complaining about.
All other solutions can only be temporary, since they require massive changes in pretty much any aspect of our lives, and they will cause massive problems in other areas.
You're basically proposing suicide for fear of death.
Actually I'm proposing life is valuable and we should protect it.
The vaccines don't solve the problem and the solutions do not require massive change, but they do require people reflect on what's important and adjust their behavior accordingly. I think that living a good life is important so I believe we should do things to better those odds, like reducing the amount of damage covid does to the body. Choosing continuous illness and your worse years coming much sooner sounds closer to suicide to me. Masking, improved ventilation and filtration, paid sick leave, and other simple steps are not absurd and shouldn't be temporary. We know easy ways to reduce massive suffering, it's ridiculous to me that people oppose it.
Anecdotal evidence but I have collected the 4 big strains and albeit vaccinated correctly it was quite the hassle each time (a week in bed or more), and yeah short of breath and more after each (once for around 3-4 months with brain fog, with the addition that I didn't really feel spicy food at all spicy during that period, just very good).
It's definitely not a joke and I hope I won't catch it again.
To add to this, SiDock is an awesome project working on an open-source, patent-free, self-stable antiviral for covid using the computers of volunteers. Anybody can volunteer their spare computational power with a few clicks. I have been crunching it since 2020 and find it very fun.
Bleach + vinegar = toxic chlorine gas that can be lethal.
Not sure how many people know this but I was in my mid-20s when I found this out, luckily not the hard way.
Also bleach and ammonia.
Basically, don't mix cleaning chemicals.
Also don't pee in bleach.
Just another in a long list of things you're not allowed to pee in!
Also, ammonium nitrate + gasoline = bad day.
I know a farmer who lived to tell the tale. He had a bunch of empty sacks, and he had piled them up and was ready to burn them. He poured some gasoline on them so that the fire would start easily. Unfortunately, he didn’t know that one of the sacks contained a little bit of ammonium nitrate, which happily combined with the gasoline and fire. Next, the mixture exploded, throwing burning gasoline everywhere.
After he managed to put the fires out he was taken to the hospital. Today, he still has some nasty burn marks on his skin, but he survived.
You shouldn't use gasoline for anything else than your vehicle anyway.
If one must use liquid accelerants, kerosene or (gasp) charcoal lighting fluid are good choices because they don't turn into gas as readily or burn as quickly as gas. Again only of you must. Solid fire starters are more reliable and safe anyway.
I think he must have left a bit out. To make it explosive, typically it needs to be in a space that will allow it to compress when ignited. That can be a hole in the ground or a large quantity in that it will create its own compressive reaction. Also generally to set it off, you generally need a shock wave type of igniter. A small amount will simply burn.
Dynamite is same way. I worked with it quite often when younger. Old dynamite can begin to sweat and when like that, it is a bit unstable. Few times just burnt it to destroy it. Otherwise you would need to use a blasting cap to set it off. That was now expensive and might annoy neighbours if you do it above ground.
Don't clean a cat litter box with bleach either.
Or a toilet. Basically anything that gets pee on it.
And not just because of the ammonia! Bleach is highly toxic to cats and they can absorb it through their paws.
Unless you are wealthy, if you think life is to expensive you should ask for more taxes, not less.
The issue is not your net income, but wealth redistribution and solidarity.
Except for the part where they just make more tanks instead of give people insulin or whatever
If you can, move to a first world country.
If not: revolution.
The United States is a first world country, and the parent comment applies here as well.
That was the not-so-subtle dig at the bullshit the people of the USA put up with.
Only the rich get the benefit of the country's wealth and power.
Something that applies when you get a little older - if you’re in a relatively specific job field, don’t burn your bridges at a job you’re going to leave. You never know who will be sitting across the table from you at the interview, at the meeting table, on the job site. People in the same field tend to move around in the same jobs as you. If it’s someone you burned, you may not get the job, or if you do, it could be pretty miserable.
I am now the client of a company I worked at for over 15 years.
Because I handled a difficult situation leaving well, we still have a very good working relationship.
It's a very niche industry, and I've worked for or with almost all the players in my region. My former employer, while small, is the best at what they do.
Yep. It absolutely never hurts to handle a situation with grace, even if it sucks in the moment.
Magnetic USB connectors are a thing and can save your cables/devices not just from wear and tear (unplugging/replugging constantly) but also from cables being tripped over or otherwise pulled. Highly recommended if you're using VR! Sadly there are no standards to these.
My dad has Parkinson's Disease, so he has poor coordination in his hands and can't plug in small cords like a charging cable.
My sister bought him magnetic USB connectors and it's changed his life! There's a small USB end that plugs into his smartphone port, and the cable connects to it via magnets. Takes my dad almost no effort; he just needs to get his phone near the end of the cable and it latches on.
There are regular charging cables and fast-charging cables. Depending on your device, make sure you know which one you're buying. The regular cables take half a day to charge my phone.
QI charging should also work well for him.
True, but magnetic cables are better. My elderly dad has terrible eyesight and low sensation in his fingers, so unless you have a magnet to properly align the phone on the pad like the iPhones do, wireless charging is unreliable for him. A magnetic connector is better because he only needs it to be near and it will just snap into place.
Are there magnetic USB-C connectors that can do USB 5Gb or even 10Gb?
There are, but are recommended against. Since they expose all the pins in a way it doesn't happen normally in the connector. If a device is not 100% perfectly protected you might send 20V in a data line that's expecting <1V, therefore frying something.
USB 5Gb/s uses voltages > 5V?
(I'm only talking about speed here, not USB-PD.)
No, but laptops often do :)
That'd be USB-PD, not USB 3.
I know.
Bonus tip: get as many as you need, and then a couple more. Sounds like I’m some kind of salesman, but trust me. I bought some to create a simple charging station for my vr controllers. Works great. Now I want some more to charge other things with the cables I already have laying around (I had some more). Didn’t have the right adapter pieced for in my devices. (Needed usb c, only had micro b and lightning). Now, a few years after I bought them to make that charging stand thingy, they don’t sell this exact one anymore. Bummer.
Which brand/type can you recommend? I want some, but I find them hard to search for.
Especially with the amazon whatever slightly matching keywords providing bogus results.
Keyboard shortcuts and basic computer knowledge. I'm in college and just existing with tech illiterate people is maddening.
Yeah IMO not so much shortcuts but file management is often lost on the old and the young.
What is a file. What is a file type. What is file size. Where do files go when you download them. What is your user directory. How do you rename files. What is a file sync app like google drive.
This stuff could save so many people so much time. Every day millions of professionals are emailing clients "Thanks for sending that though, but it looks like you've emailed me a shortcut instead of the actual file."
That article is completely accurate, I see pretty much everybody save their documents on the desktop but if I were to make them find it in the file explorer they wouldn't have a clue where it is. With macbook users they just use the search feature and probably haven't seen a directory in all their lives.
The people at my school call all laptops "chromebooks" or "macbooks" and only do their stuff using the Google web apps (docs, sheets, slides, forms, etc). As a degoogled and pretty savvy individual it kind of hurts my soul as I'm over here using stuff like libreoffice on my Linux machine.
Yep, that's precisly my experience from uni as well. And it wouldn't be a problem if this "alternative mental model" worked for the people applying it. But it doesn't. They keep losing stuff, working on 5 different copies of an essay, not keeping track which one is current; they just add workload to everyone collaborating and then someone has to handle this shit. And who does it? The techy "nerds", such as you or me. The iPhone, iCloud and Google Drive really fucked the people who will have to at some point work professionally with GenZs (speaking this as Gen Z myself)
I got a contract to produce some exhibits for an event at a university. These exhibits included some touch screen information kiosks that would allow guests to find out more about the exhibits. I used some software that was kind of like turbocharged PowerPoint; it could do graphical things on the screen, it could run other applications, running on a Raspberry Pi it could handle the GPIO and blink lights, run motors, whatever.
I built the exhibits themselves and rigged up this framework, a student from the university was assigned to actually generate the content. Each of 4 exhibits was to get 3 or 4 video files each. From this student, I get about 5 emails that each contain two or three video files. There is no coherent naming scheme, "video1.mp4" "hector.mp4" "version 2.mp4"
So I call up this kid and ask her how I'm supposed to know which of these videos goes where in what exhibit. "Watch them and figure it out I guess." Even if I had time for this, which I didn't, that's outside the scope of my contract. YOU organize them into something like "exhibit-1-video3.mp4" and I will put them in the places they're supposed to go.
I feel for the professors that have to deal with the work these kids turn in.
i still remember when i learned ctrl c and ctrl v in school, that moment was unforgettable because its a basic skill
One for people in the US:
You aren't taxed at the higher rate for all of your income when you get a raise that puts you in a higher tax bracket, only the part that is in the range of that bracket specifically. The rest of your income below the bracket is taxed the same as before.
I've seen a lot of people decline promotions and raises over this, and bosses are very happy to let you continue thinking that's how it works.
Not sure if that counts as not common knowledge, but a lot of people I know didn't know it before.
While that’s true for taxes alone, there are income gaps where a small increase of income can result in a loss of various benefits that were worth more than the increase. This can be things like food stamps, subsidized rent/childcare, etc… People end up stuck because while they could potentially earn significant advancement and increased wages over a 4-7 year period, they’d have to weather a significant deficit through intervening years.
Ideally there should be no cliffs, and all these social programs should have a sliding scale of benefits so a person can always benefit from increased income. Part of the problem is they’re managed across multiple levels of government that don’t always play well together, and a sliding scale might mean more benefits paid out to people that don’t currently qualify. That’s probably actually a good thing, but gets spun politically as undesirable.
When you're about to face a high risk, high reward situation, you should willfully, willingly start to hyperventilate, as this helps your brain …
NEVER take any stranger's advice on the internet as credible without checking it with a specialist. This is especially true when said advice relates to your health and/or safety.
That seems like good advice…
I guess I can't trust it. Since a stranger in the internet told me eh? Lol
… without checking it. If that's your understanding, you're correct.
On the affirmative, ALWAYS check whatever advice you hear/read on the internet. Be ultra careful with your health and safety.
Sounds risky, but the rewards are limitless.
Most microwaves can be muted so the button pushes are all silent. You will have to look up how to on each microwave model but almost all models have a mute option.
A partner of mine has an above-range microwave with the worst implementation of this that I've ever seen. When you mute the button beeps, it mutes the entire microwave. Food finished cooking? Silent. Manual timer set? Hope you're looking to see when it hits zero. There's no way to silence the buttons without muting all alerts completely.
Ugh, that's how mine is too. All the noises or none at all.
Usually its holding start and stop buttons for a few seconds
I read somewhere you just have to long press zero on most model to mute them
Is this a joke my microwave is too analog to understand?
What wasn’t reasoned in, can’t be reasoned out. Many people who suffer from conspiratorial thinking need help and support more than evidence and debate.
In Windows 10 & 11, window+shift+S then draw a box to grab a quick, pre-cropped screenshot. It goes to your clipboard for easy paste and you get a notification you can click to view and save to file.
Bonus: use window+L at work to lock your desktop, preventing shenanigans.
Yeah, but they removed the "Ctrl+Alt+cursor" shortcut I used to use to punish people for leaving their computers unlocked.
That was part of the Intel integrated graphics program, not Windows.
What did this do?
Changed screen orientation. The cursor indicated which part of the monitor was the top of the screen, so with a standard monitor config "Ctrl+Alt+Down" flipped the screen, for instance.
Ahha of course. I remember using this to mess with people when I was in school. Thank you
Lol it's still around, a graphics tray shortcut or something
I keep learning this exists and then instantly forgetting about it…

Cement is highly alkaline. If wet cement comes in contact with your skin, it can cause third degree chemical burns. So don't write your name in wet cement like Bart Simpson.
Yeah, use a stick, not your fingers.
IDK if "third degree" chemical burns are a thing.
Cement will dissolve the fat from under your skin, and a third degree burn is when you cook the fat under your skin.
Also it's not going to burn you within a few minutes the way we normally think of a chemical burn.
The "degree" is based on the amount of damage done to flesh, bone, and skin. Each type of burn has different criteria, so yes, a third degree chemical burn will be different from a third degree flame burn, which will in turn be different than a third degree steam burn.
Bullshit.
If you have a coherent rebuttal, I'm happy to listen. If not, Johns Hopkins has a good page on the subject.
I had a quick look at this which basically says that you're right and I'm wrong.
Additionally, it lists sunburn as an example of a radiation burn, which is kinda neat.
deleted by creator
How about this - your position is that a chemical burn from concrete cannot reach third degree? That it doesn't happen fast enough to cause that damage?
Let me use your vernacular.
Bullshit. (Warning: NSFW)
That's not what I said at all.
