At 51 I feel all of this so deeply. Throw in a few seismic life changes (divorce, moving, and more fun stuff) and I contemplate my approach to life on a constant basis. Sometimes I think it’s because of the divorce. Then because two of three kids are in college. Then because I’m 51. It’s all, of course, but it helps me to remember there’s a reason midlife is so often addressed in the world.
