I am 54 and have been exercising since I was 28 and I can definitely vouch that I feel, look and act younger than my friends that do not exercise... Just the other day I was showing some vaca pics to my mother and she mentionned that the couple we went with look so much older than DH and I, when in fact they are quite a few years younger than us

... It felt good to hear that...
So in a nutshell YES you will definitely feel better
