Yeah I remember some txt files floating around the BBS' in the
   early 90s telling you how to build your own cancer curing kits
   for cash from radio shack and how to promote them to people.
   Used ultrasonics combined with a little 9v shock thing - similar
   to a TENS muscle making device. [had one of those TENS things -
   before ebay banned medical stuff... 15 yrs ago lol]
