Interesting notes / anecdotes from me about 10,000 hours and genetics.
I played golf at a pretty high level throughout high school and college. I practiced and played golf on most days for 8 straight years. I'm sure I reached 10k hours. Currently, I don't have almost any time to practice and play golf. I haven't practiced or played regularly in at least 6 years. Yet, playing once every 2 months or so I'm still able to shoot at or near par most of the time. I suspect this has more to do with the 10k hours of practice than my natural abilities. Not really any way to prove that, but I suspect a similarly athletic person who hasn't put in that practice wouldn't generally shoot par playing 6 times a year.
