What colour are the Uncle Alp's nose hairs? Whity with no doubt?

アルム御爺の鼻毛は何色なんやろう? やっぱり白?

I've been thinking of such a silly question, just because I found myself with some whity nosehairs... Why my nosehairs became white first, while my hairs didn't? Or my mustaches, beards and whiskers didn't? (I don't grow 'em though)

というアホな事を考えているのは，さっき自分の白い鼻毛を数本発見してしまったからです． なんで髪の毛やヒゲは一応まだ黒いのに鼻毛が最初に白髪になるんやろう...
