Hi, I always wanted to play football but never had the chance.. I am from Ukraine, we didnt have any team there. Now I am 28, living in DC, and still want to try to play. Obviously, I do not aspire to become a pro or anything like that, but I still want to play. Now, what should I do? Or this is a stupid idea?
I am 6'5 tall, 310 pounds (not just fat, bones and meat too), previously was practicing boxing (ab 4 years) and judo (couple years)
Thank you
