You’re absolutely right, there are a lot of things I’ve gotten more adept at in the last few I wouldn’t have thought possible just by making myself do it.
That said, my feet have insanely high arches, and the tendons are too short, causing them to pull and tear. I do stretching for them, but it only helps so much. Inserts are a Godsend. I also have herniated discs in my back, which sucks. Most of my problems, however, are just because I spent my whole childhood and teen years (…and 20s into my, current, 30s) very heavy. It’s not easy on the back. :/ herniated my first disc at my lightest/healthiest weight at 14, oddly enough, though.
