RE: Besides cars, what is your favorite hobby?
HeyItsWes, good for you. It will keep you bones/muscles and tendons strong. I have been lifting weights in some fashion or another 3 times a weeks for several decades now.
Don't forget the cardiovascular/flexibility side of staying in good physical shape.
So besides physical, also include mental and spiritual as well and you will be well rounded.
