Why should wrinkles be unpleasant to look at? Why struggle to reverse the signs of ageing?

Wrinkles, grey hair etc are perfectly normal in older people, and ought to be universally acceptable.

I can never understand why anyone would purchase products which 'reduce lines' or 'cover grey hairs'. Or undertake cosmetic surgery, unless one is severely deformed or disfigured.

I have never in my (long) life used any products like this. I'm pretty sure I don't frighten people in the street, and look quite ordinary and normal for my age.
