He says "Go Green!" several times in the talk, and he's referring to using SuperGreens.
I actually learned all about this in 1998 at his 10-Day Life Mastery course on the Big Island of Hawaii, where he brought in Dr. Young and provided all of us participants (several thousand) with free SuperGreens every day.
Tony wanted us to experience the difference without risk or cost, and I was hooked. That was such an inspiring time for me, and I've used SuperGreens ever since.
