I have a theory that men who wear hats/baseball caps,woolies etc from a young age and wear them regularly,are more prone to become as bald as a coot, than men who don't.
I have never worn hats of any kind, even when it's baltic. At the age of 51, i still have a good mop of hair. Most of my mates/work colleagues who don headwear, are either shiny heads, or heading that way.
It is said that a lot of the bodies heat is lost through the top of the napper, but to me, that's a natural process and stops overheating. I think it's more important to let sunlight onto your bonce.
Any thoughts?
