I presented at the October 2007 EFT Mastertraining conference that took place in Boston, USA.  I know it is a little belated but here is one of the pictures that I brought back with me.

Gary Craig the developer of EFT did a post conference day demonstrating EFT on stage with volunteers. The volunteers were wired up to monitors so the audience could see the changes in their brain waves as they happened.

All the best,

Tania
