As I've got older, I've developed chest hair to rival a mountain gorilla.....I'm sure it must have some evolutionary significance, but would be a right bugger to keep shaved.
Yeah, there is also the question of increasing nostril and ear hair with age which has started to annoy me.
In the words of Billy Connolly, "what does my body know that I don't? What do I need it for?"
:x
I read an article about this, which was somewhat surprising, apparently as you age, your body recognise this and responds by producing more testosterone....hence the rapid growth of nasal hair etc.....it also explains why us old buggers can give a bird a better time than the young lads.
