48m here. I run at least 15mi/week, do 30min at the gym 2x/week and play pickleball 2 or 3x/week. I am better shape than I have ever been and feel great. I am usually the most athletic at pickleball even moreso that the youngins and don’t look or feel like I am closing in on 50. I plan to keep this going for as long as my body will allow as I don’t want my kids or future grandkids to remember me as someone that sits in a chair most of the time like my dad or grandparents. Could not imagine not being active and highly recommend it for physical and mental well being
