A common one is the tying of one's shoelaces. It's pretty common to tie the knot in an unbalanced way. https://www.fieggen.com/shoelace/grannyknot.htm

This was so confusing to me. Don’t American kids learn how to tie their shoes properly? Here in Germany, I was taught that in kindergarten.

You aren't supposed to rinse your mouth with water after brushing your teeth. You're supposed to spit excess, but leave the toothpaste on to absorb.

Ahh, mine is an interesting counterpoint to this!

I had canker sores for my entire life, well into my late 20s. I tried everything: changing toothpastes (more on this in a second), changing brushes, using mouthwash, being told my mouth was "dirty" and I need to brush more, etc.

Turns out (at least for me) the sodium lauryl sulfate (SLS) used as a foaming agent in (almost) every single toothpaste causes canker sores. I found "canker sore toothpaste" that lacks the SLS, for $7 a tube. I used it for couple of years and it worked!

If you read up on SLS, this is not super-surprising. It's a known skin irritant, and is known to cause more irritation when left on the skin for more than a couple of minutes. Canker sores are an autoimmune issue, so my theory is the irritation triggers an immune response, leading to the sore.

And then I discovered if I rinse thoroughly (twice) after brushing, even with normal toothpaste, I just don't get canker sores anymore! Not sure if it's universal, but canker sores suck so much, I hope this helps someone suffering like I was.

When my then-gf/now-wife and I first moved in together, I got really mad at her because she kept "hiding" my stuff when I left it out for more than a day. I couldn't find anything! At some point, I yelled, "It's like you don't even want to see any of my things when I'm not using them!" Then I stopped for a second. For the first time in my life, it made sense. The whole point of putting things away is to hide them! No…

I used to complain to my mom that I left stuff on the floor on purpose because I could find it faster. 30 years later my daughter said the same thing to me and I just nodded and shut her door.

Staying warm. In the winter, I used to stay warm by turning up the thermostat. Then I discovered (via HN) the Low-Tech Magazine article, "Insulation: first the body, then the home." [0] The article argued that it's much more efficient to focus on heating yourself rather than your whole living space. I invested in high-quality wool clothes that I wear in layers and warm slippers. Now, I keep my home about 5 degrees F…

I think one problem is managing moisture not to get mold at home.

So most likely you still need to keep heating on but it might not need to be super high - just enough to have convection from heater moving air at home and having some ventilation letting in a bit of outside air in and warm one getting moisture out.

My wife and I have a rule, "everything needs to have a home." Because if it doesn't have a home, it becomes clutter, and after enough clutter, it finds a home... usually a sub-optimal one, like a junk drawer. The kids (4 and 5) have adapted to this wonderfully. It really helps them. It makes cleanup a trivial task because everything is known to belong somewhere specific. Related to this: the recognition that everythi…

We call this the OHIO system. Only Hold It Once. Don’t set things down in random spots, pick it up and it goes where it belongs.

The issue is it doesn't work for people who tend to sweat easily.

I'm one of the sweatiest people I've ever met. I've slowly gotten better at layering and how to use clothes for different situations, but I agree it's a big factor and there's some unwinnable combinations.

For instance, I've finally learned to embrace "long-john" style long underwear under my pants, but it's only possible because I'm working from home. They are amazing layers for warmth, but unlike additional shirts, hoodies, jackets, scarves, hats, long underwear can't be casually removed. You have to take off your shoes and your pants! So if (when) I was going into an office, I always made the choice to have cold legs during the commute but comfortable legs all day. Now I can wear them in the morning, take them off if the day warms up, and put them back on whenever the temp. drops again.

But overall I'll echo a few comments in here that some of the more expensive gear, even as base layers, really is better technology. And getting to know my body and my situational habits, it's been possible to figure out layering clothing that worked for me, but only because I was working in tech and felt like I had enough money to get it wrong a couple times... If I were still living on a student or even "average" budget, I would've been much shyer about trying some new $30 shirt just to see if it agreed with me.

Not using a bidet. I honestly feel like the single biggest quality of life improvement I've had in my adult life was realizing how much of a difference a bidet makes. That, and using flushable wipes when at home instead of just 100% toilet paper.

Flushable wipes aren't flushable. It's a bit of wishful thinking on the part of marketers. They really do clog sewars.

You know you’re in a long term relationship when your better half starts throwing away your stuff without asking.

That's a good way to make me strongly reconsider being in that relationship.

Not using an electric toothbrush. First time I used one it felt like I'd had a proper dental cleaning. An extremely half-assed effort with that kind of brush beats a thorough one with a manual brush. I thought they were a gimmick, but no, they're amazing.

This. I discovered electric toothbrush in my mid 30s, I have good teeth and brushed already with regular toobrush pretty good, but to be really thorough I had to be always tired after brushing, now with electric toothbrush I can achieve same result with less energy, less tired.

Btw. I went through bunch of cheap noname toothbrushes to realize there is reason you pay for Philips and Oral-B brands, all cheap toothbrushes will fail within few weeks/months due to humidity or other failures, didn't have such experience with those two famous brands, wife and me use Oral-B Pulsonic Slim for years (extremely slim and light, but less powerful), for son who had problem with teeth I bought a bit better (heavier but more powerful) Philips HX6511 (still quite cheap, next time I'd buy this also for myself). Daughter has still cheap Xiaomi, waiting when it will finally break (from 4 I bought 3 broken), then will probably go for same Philips.

Btw. be aware most of the electric toothbrushes still use old NiCd batteries with memory effect, so to achieve maximum battery life/longetivity you should NOT leave tootbrush in charger, but charge it only when it runs out of battery, if you keep it in charger stand it is significantly decreasing battery life with each charging to the point it is useless already by the end of warranty.
