Damn....I guess the secret to aging gracefully is staying active. I still hit the gym every other day, play pickleball, work on my hot rods and still ride my Harley on a regular basis. Oh yeah, and chase bad guys part time...
Have I slowed down a little? Sure, but the secret is to not give in to it. It's too easy to put your ass in that recliner and say...fukkit, Ill get to it tomorrow.
Unless you have actual health problems, use it or lose it applies to old age.
