You better learn from "them old people" ^^Þ
They'll probably will live more than these newer generations x)

And You should definitely watch the videos, don't lose the knowledge!!
( ..well, just saying cause I don't want to assume anything about You, since we haven't had any previous interaction that I'm aware of = ·.. )!!

I must say that what gave me back hope to treat/cure my spinal problems, were indeed Dr. John Bergman, Eric Dubay, and a couple of friends of Eric ( I can't recall the names now =x.. but here is one of their videos, uploaded by Eric, pinned in my twitter.. )

All the best, and have a great time ;),
