The guy who showed this to me said earth people (sorry, sometimes we call you guys that) often do not get this or think it's stupid. One reason I'm sharing is to hear some thoughts from people who are not in residential drug rehab.
Thanks. This fascinating and illuminating. I recently learned of the death (25 yrs old) of a former student of mine. He was in my class as a 4th and 5th grader years ago. I've not yet learned the specifics, likely an overdose, but I think I can see some patterns between his behaviors and this video.
