I’m confused. If physical exercise is so vital for the brain how come one of the smartest men on the planet does less physical activity than the worst couch potato in the world. Nobody can accuse Professor Stephen Hawkin of being dumb. How does he keep his brain fit when he doesn't do a much as flip channels with his hands?
Then think about Einstein, not very buff and smoked a pipe. Is this just more moralising pseudoscience -- self-agrandising garbage concocted from pet theories and bad use of stats?
