It looks like I haven't posted here, but I did vote on the poll already. Let's see, I would have been about 28 when I started. About the poll results, there are fewer people who began later in life, which I think is to be expected. Roughly 50% started by age 15, but about 32% started between 16 and 29. That's a pretty good fraction that didn't begin as children or young teens. I thought that was kind of interesting.
