Well great, I have physical decline to look forward too as well. Just when I was working on being able to do handstand pushups again (its been 20 years). I am actually close, but I probably need to drop down to at least 250 before I am successful.
I did decide against getting back into playing lacrosse... I remember playing pickup games with older guys when I was in college. One time a guy looked at me and said "dont hit me, I have to work on monday". That resonates now.
