Just some questions regarding recent episodes.

In a recent interview, the topic of autism was discussed and the guest was making points about how autism can be reversed with certain treatments. This clashes with the traditional understanding of it as a developmental disorder and I just wondering where I could find more information regarding that. On another note, Greg was recently talking about the structured water filter he uses for his home, I was wondering if anyone knew the name of it or where a person could buy it.

Thank you,
