I kinda have to call Bullshit on this one. Other than Einstein none of the others had kids that we know about. So when you say we all have the same amount of time in the day these guys never had to chase after there spawns all day. I guarantee that sistine chapel would never had been finished if Michelangelo had to get home and help with the kids. JUST SAY!!

I agree with the above. Not to mention, each of those individuals was employed in the fields for which they became famous. It simply isn't true to say that Da Vinci and the average Chiver have the same number of hours per day with which to achieve greatness, when one of those individuals has to spend at least 40 hours a week working just to pay the rent and purchase gas. Times change.
