What are some examples of 'common sense' which are nonsense?

No, I'm responding to regular people. Your immune system is way less effective than you think, hence the wrong common sense part.

No. At least, it's not the general cause of 'middle age spread'.
The base metabolic rate refers to how your individual cells respire when at rest. And a brain cell in 20 year old respires much the same way as a brain cell in a 45 year old. Same for all other organs. There is a gradual decline but it's on the order a single percents.
Organs and tissue at rest respire at different rates, so some of the change people notice is due to change in body composition. Muscle at rest burns twice the calories as fat however this is still only a minor contribution.
Base metabolic rate doesn't vary much at all. The vast difference in daily calories consumed as one ages is general activity level.
Overall metabolic rate = base rate (varies a little on body composition) + calories burned in general activity (varies a lot)
People typically are less active between 20 and 40. This is not just sport but also lifestyle. People become more efficient in their habits as they age. They drive instead of biking or walking. They sit in the sun on holiday with nice food and wine rather than dancing all night. Etc
Lifestyle choice is the primary cause of excess calorie intake and 'middle age spread'. Not "my metabolism that I can't do anything about".

it also means don't risk everything you have for a somewhat opaque promise of something better

Well it finally changed the 8th time I pressed it, so checkmate.

No.
Getting sick without already being immune leaves your body trying to speed-run anti-body development, while ALSO fighting the disease using more basic physiological responses.
And even with anti-bodies, you're not actually impervious. You can still get sick with diseases you're "immune" to, as even deployment of disease-specific anti-bodies is a complex biological process that can go wrong, come too late, or not be enough.
Given time, a person can develop "immunity" against a lot of stuff, but that still doesn't mean every cell in your body is then changed in a way where that pathogen just bounces off.
You see this most recently with Covid, as people who are vaccinated still get infections, but unlike with unvaccinated people, the body fights it off in a couple days, rather than a few weeks.
But it does still takes those couple days for the latent immunity to kick in, and for the body to deploy that defense.

I switched keyboards on android, new one doesn't have autocorrect or swipe, but it doesn't connect to the internet. I don't always proofread posts.

Common sense itself.

They are more similar than they are different though. The numbers are bigger and the limits aren't known, but they do exist. Many countries have felt the pain of excessive debt, the arguments that it can't happen to the US are essentially that the US is a unicorn country.

Pot committed is more a math reality with a small amount of sunk cost fallacy. There's always a non zero chance someone is bluffing. A 99% chance to lose $11 is better than a 100% chance to lose $10 if you can win $100 on that 1%.

EDIT: Basically the immunity system doesn’t work like a muscle.
I think the immune system can be likened to a muscle if someone really wants to go with that metaphor, but only if you consider vaccines to be the gym and getting sick is uncontrollable and dangerous physical exertion. So, wanting to develop natural immunity is like wanting to get into street fights to build arm strength. It might kinda work, but you'll also be in a lot of unnecessary danger.

In a traditional long bow yes. In a modern compound bow, not necessarily.

If everything is equal, the arrow gets out of tune. If you tune the arrow it becomes heavier.

Same goes for most "close door" buttons in elevators btw.

The birthday problem is super easy to understand with puzzles! For example, how does laying out the edges increase the likelihood of a random piece to fit.
