“These examples of [adjusting] physical activities are relatively straightforward. Bodies age and we have to change how we think about success or we'll always be failing. I think these examples are worth discussing, though, because they make an important point: we don't always see these necessary changes as changes; instead, we think of them as quitting or capitulating. Why? We don't have to see changes as capitulations, and it is often better not to. ... In other words, I'll be better off thinking, "I value my health and I'm finding new ways to maintain my flexibility as I age" than "I used to love yoga, but I've given up.”
