I'm acquiring new passions all the time. My favorite exercise, and I engage about 3-4 times a week, is tennis. Started about 5 years ago and absolutely love everything about it. Great for forming social friendships, too.
I'm working on a novel, play some piano (novice level), love to bake (was a career chef-now retired), and practice some rudimentary yoga stretches (it helps with the tennis).
btw...great question to put out there.
