An essay (no study behind it): a skier jumps a 7ft cliff instead of 5ft, mid-divorce, and the divorce feels smaller afterwards. The claim is that succeeding at something physically risky updates your sense of what you can handle.

Oncologist Siddhartha Mukherjee's reframe: think of ageing diseases, osteoarthritis included, as "regenerative failure", tissue losing its ability to repair itself, rather than a list of separate diseases to prevent.
