I don't have a lot of hobbies. I don't play golf. I don't have any children. Things that occupy people's time. I just try to take jobs.
It's fair to say that Jews dominated basketball and that started in the 30s in all the big cities. I think it was simply because Jews lived in ghettoes and basketball is a great schoolyard game. You don't need a lot of space or equipment and you can adapt it to how many players you have.
