I always like to have this interesting conversation with gray/silver haired guys, telling the ones in whom I see "hotness potential" to dye their hair. I tell'em go back to being brunette, you're going to look smokin hot, the ladies will be all over you!!
To which they always reply the same boring standard explaination, "But my gray hair makes me look "dignified", it gives off a impression better at work, you're more respected blah blah ....ok so I kind of sort of get that .....but DON'T YOU WANT TO LOOK SMOKIN HOT??
Ok so let's examine 2 possible explanations for gray hair
Biological - loss of protein
Spiritual - they say it's a sign of enlightenment, advancing up the human ladder,
....AS YOU REACH CLOSER TO DEATH
Forget dignity
Dye your hair
