An age limit? Who is to say what is the limit? I played my first year at Milford at age 20 and was in awe of some players that were over 40. I am 44 and now play steadily at CAJA in Connecticut and share the cancha with several of my former rostermates, most of whom are in their 40's, as well as many amateurs over 40, and believe me, we can still play some ball. One of the attributes of our sport is that physical size, strength, or age is irrelevent, you just have to have the talent.
