IT is estimated by neurologists and psychologists that we use roughly 10 percent

:-) I think that I am using less than my ten per cent! and, like me, a lot of people use less than ten per cent. I don't know what is for the the other 90 per cent but for sure I'd like to know why our brain capacity is so big and our use is so... small. Is that just for storage as the hard disk of a computer?
