In my adult like, I was never interested in gambling, until I had some really bad luck that negatively impacted my health, my energy level, my earnings and my forward progress. I became vulnerable and tempted by the "Hail Mary pass" to so-called luck, known as gambling. So from age 18 to 50, no interest in gambling. Then my personal bad luck and low energy coincided, time-wise, with the building of a new casino where I lived in Pennsylvania. I then became a gambling obsessive.
But I look back on my childhood. I did like to bet, when I was in grades 5-8. Not for large sums. Just a dollar here, a dollar there, on football games, mostly. Sometimes on heavyweight famous fights, like Ali vs Frazier. I thought at the time it was just for fun. Maybe it was. My dad was also an influence. He used to bring home the football betting sheets. He got a commission on them. He was an intermediary with the bookie. But at that time, I guess I wasn't obsessed with betting, as I didn't continue it into high school. Later in life though, I became that disgusting thing known as a gambler.
