We have quite a bit of ability to control things. All my friends who are into fitness enough to cite a PR seem to have constant random aches and pains.
People who just walk and eat healthy but never push themselves have much less.
There are some scientific benefits to ice baths, and I do take cold showers(Anything to defend against the viruses here!), but you won't see me "Playing through the pain" or quitting a job to hike for 3 months.
I do think absolutely everyone should read Taleb though. Both for the few useful ideas not commonly found elsewhere, and because you'll see antifragile thinking everywhere and have a better understanding of other people.
