Well, now that you mention cavemen. Historically, in the findings of our ancestors, it has been found that the brain started to develop rapidly about the same time as our ancestors went from being scavengers to being hunters. Coincidence?!
However I think we should drop this and get back to Autifony and the bright future it might bring to us!
By the way, am I the only one who thinks it's just a matter of time now before we have a drug that might at least alleviate our suffering? I mean opposed to let's say 10-15 years ago there was nothing. Now we have Trobalt. We know it does something. And now there is this Autifony lady that has had her T. reduced by 75%.
Even if Autifony doesn't work as we all hope it will, there's allways Otonomy, SciFluor, Bivarectam... and so on and so on.
Therefore I think that in 5 years at least 2-3 drugs will be out. I haven't been this positive in I don't know how long and I pray I'm right because my T. has been acting up in 2015 so far so that relief can't come soon enough...
