This is something i've been wondering. I understand it's cultural depending on the country/area, but do you hide your age for fear of judgement, or do you just not care about people knowing how "old" you are?
For example -- women, depending on culture, hide their age, or get cosmetic surgery to make them appear younger. This is hardly anything new, and that's their choice and all, but I don't see a real reason to hide or lie about your age, except for vanity reasons.
Obviously, there are more than a few scenarios where your real age might impact the situation, both good and bad - but i'm talking more about the vanity aspect. What makes 30 so bad? or 45? obviously people are afraid of their own morality and therefore don't want to grow older, but ... what makes your real age so horrible?
Then again, people say I usually look young for my age, so I have no idea if i'll feel the same way as I grow older. I hope not. :]
