Hey Erin, thanks for this blog. I wonder about certain neurological diseases like Autism? Autistic people don't seem to be aware of their condition at all (in the way a neurotypical person would know they are blind or deaf or have cancer). Since Autism is almost an epidemic now, do you think that maybe it is more environmentally triggered? Just curious. Don't know if that makes sense, but I would love to hear any additional thoughts if you have some time.
