So true. I was doing a financial analysis of American professional sports a few months ago. I assumed height was a known variable (which is true; a doctor can predict a child's adult height within an inch), but talent was dependent on hours spent practicing (the whole 10,000 hours thing). That's all that really matters. What I came up with was that you have to be something like 6'7" or taller to have a reasonable shot at success. If you're going to be this tall or taller, it becomes a wise investment to work at becoming good at football, basketball, or baseball. By this I mean you have a reasonable expectation (like 1 in 5) of getting drafted to a major league.
