Everything I say is monumental.. :p

I am (well, was) a scientist, so I'm a bit defensive when it comes to claims about science. I accept that it may be a novel concept for some, but to claim that this is new to science isn't correct. Clinical psychology, psychotherapy, CBT etc have been around for over a hundred years.

Epigenetics is an interesting modern extension of genetics but you have to be careful making direct claims that thinking a certain way will necessarily trigger an epigenetic switch. It's certainly possible I'd guess, as 'thinking' is nothing more than a biochemical process in the body, and as such could be part of an environmental trigger. Isolating such a thing, though, would be incredibly difficult, I'd imagine.
