I saw a woman at the grocery store with significant hair on her upper lip and chin.............I wondered "why don't you do something?" It's not going away.
That's because at the same time as the facial hair starts growing, the eyes start deteriorating. So you can't actually see the hair yourself. Until one day you catch a sideways glance in the mirror and - whoops - you know by the length of the hair that it's been there for a while.
