It's funny how gambling is a big part of all sports, but mostly underground.
I gambled on football one season (97) and made a bit of money, but I really don't understand how people get addicted to it. I treated it like any other job I would do, and that's what it was, work. Hours of checking stats on line. A complete grind. I made money, but my hourly rate was very poor!
But I guess the true gamblers go on gut instinct and get a big dopamine or endorphin rush, and that's what hooks them. Not for me though.
