Looking younger than you actually are

[Dexter]

Havent you noticed that really social people look okder than they look? Its because they have a lot of social experience under their belt thus making them appear older.

Are you really sure about that, because I don't think that these two things correlate?

Is there a scientific proof for this?
Like for example: Social interaction causes the human body to produce a certain hormone. And a side effect of that hormone is that your skin and body is aging faster than without it.
