I'm 43. Like I said, I don't know anything about this - just some thoughts and ideas to consider (although, I do know that autism has been hugely redefined, which has lead to a huge increase in numbers beyond just increases in actual cases). It's probably some of everything. I would just say that it's not smart to jump onto any one idea as "the answer" like this dope did. Life is more complex than that and not every statistic is what it seems (or what it is portrayed to be).
