We circle back to the documentary "Cliff 20". Since our audience has grown so much, I wanted to re-introduce Technology North and their CEO Ling Huang, the center-point of Cliff 20. Also, the documentary is free on YouTube, and I highly recommend it. Also, I re-play a quick clip from Dr. John Young, who has a fascinating tip about Vitamin D, which I think is so under-discussed in the Autism family community.
