Okay my 4 year old gambling  story.  I was the youngest kid in kindergarten. In September 1961 I was 4 years and 8 months old.

  We went to a school in Brooklyn.  So the game I was taught was  flipping baseball cards. There where multiple versions one was matching colors of hats on the players.  I am colorblind so I was playing a game that I absolutely could not win.  I would lose all my cards every single time. When I asked to play other versions of flipping base ball cards.  Ie a finger flick with multiple rotations  on the way to the ground landing heads or tails. No one would play that and not knowing a freaking thing about compulsive gambling I had to play to get even. It took me a long time to learn to not play that game of matching for colors. . Plenty more stories after that one.
