Why not? Everybody ages and there is nothing to be ashamed of it. It is a natural phenomena. What is black today has to be grey someday unless you die young. But, not many accept ageing gracefully. Getting old makes them depressed. I have seen many people who just want the wrinkles off their faces.

Normal beauty treatments like facial and bleaching can make no difference to the skin once you are old. Make up can temporarily hide the wrinkles, but is definitely not a permanent solution. Well, costly cosmetic surgeries do make difference, but is it worth the efforts?
I don't understand why people don't accept ageing. Why can't they feel beautiful in a wrinkled body. Why is always young considered beautiful. There are many questions that don't have answers and this is one of them.
