hehe. nah, age has nothing to do with overall fitness.
initially, i thought it is natural that one's performance decline
as he grows older until we matched against a team of 30-40 year old
folks (smokers with beer bellies). they taught us a good
lesson.
of course one cant expect to run tiredlessly after not having to
play for a long time. but once you play regularly, your fitness
will naturally come back.
