This is just my opinion, so don't shoot me, but I do think that certain people have a more addictive personality. By that I mean they can easily become addicted to something, be it drugs, alcohol, gambling, or fish bait collecting. I am one of those who has a a addictive personality, but I can control it to a fault. I can easily just drink one beer a night to calm the days aggravations, but racing dirt bikes was my drug of choice and I dumped tens of thousands of dollars doing it. I race injured and would do anything that wasn't illegal to get enough money to race on sunday. I since have stopped racing, but there isn't a day that goes by that I don't wish I was back out there, and I know if I still raced it would be a divorced single man, because there was not time for anything or anyone else.
