Probably both Ed... brain dead AND brainwashed... OR maybe you need to examine YOUR own beliefs and perceptions about your preconceived notions of "effectiveness", physical limitations... and perhaps contemplate what true human potential could entail.
Perhaps, lots of things defy explanation, and many people believed certain things were improbable and impossible... like... flying (from da Vinci to the Wrights), much less flying to the moon, or that the Earth is not flat and revolves around the Sun.
But hey, whether you believe or don't believe is up to you.... and better if you don't. If you are happy with whatever level of accomplishment you're at, then more power to you.
Me? At least I have something higher to aim for... and if I miss, well so what?
BTW, have you gone to see Dan yet???? Or maybe you're just happy not venturing out of your own comfortable little box?
