Do we look younger to ourselves then we look to other people?

I have wondered about such things. I feel younger than my chronological age. I have more energy than the majority my age. People say this to me too. I look in the mirror rarely. I don't wear make-up except for lipstick or gloss. Rarely make-up except for weddings, parties, etc. I think I am aging slowly. Thanks to my mom and her great genes. And to life.
