Good news for Grey Hair

In the book called "Fooled by Randomness" by Nassim Nicholas Taleb (page 63) he states, and I quote:
" I was amused to discover an evolutionary argument in mate selection that considers that women prefer (on balance) to mate with healthy older men over healthy younger ones, everything else being equal, as the former provide some evidence of better genes. Gray hair signals an enhanced ability to survive- conditional on having reached the gray hair stage, a man is likely to be more resistant to the vagaries of life. Curiously life insurers in renaissance Italy reached the same conclusion by charging the same insurance for a man in his twenties as they did for a man in his fifties...once a man crossed the forty five year old mark, he had shown very few ailments could harm him".

Maybe this could present a new marketing opportunity for manufacturers of grey hair dyes to expand their market to younger men!
