The amazing part to me is the rise of autism/add and similar health issues in people today vs. 30 years ago.
30 years ago it was odd to hear about someone with ADD/ADHD/Autism etc. Today it seems to be the norm where almost everyone knows someone affected. So much of the media and buzz is fixated on the symptoms, but not the root cause.
Call me a nutter, but I think it has a lot to do with food and diet (and the lack there of) in today's general population. This isn't necessarily associated with the ones named above, but I mean it in a grander sense.
But don't you recall kids 'back in the day' that seemed a bit off / uncomfortable at school? I'm in my late 40s, and I can certainly think of a few kids back then that would tick the boxes of an austism/aspergers diagnosis.
