Yes. 39 here and I feel better now than I did in my 20s, and I can run a mile faster now too so I at least have some objective evidence I'm not totally fooling myself. :) I'm far from svelte today but I've really improved my life by taking better care of my health. To everybody in their 20s: the health-related stuff you can get away with in your 20s (poor diet, no exercise) might be working for you now but it's not going to fly forever!
