Older. I've always looked older than my age, which was great when I was in my teens. Not so great at 38. I've always acted kind of like a grandma though, so the way I look at it is that now my body is growing into the role
But I do envy people that look young.
Here is an embarrassing example of how I've always looked older--I was 21 years old and 7 1/2 months pregnant when my now ex-husband and I bought our house and the neighbors thought I was my ex-husband's MOTHER!!! He is 7 years older than me, by the way!
My kids must have got some sort of accelerated growth gene from me because they struggle with the same thing. I fully believe that my 16 year old son could walk up to a bar and not get carded. He started puberty pretty early and now he is 6'2" with a full beard. He was 15 years old on our last Disney trip and no one believed he was a minor. In fact, when we got to the boarding area at the airport, Southwest thought he was his sister's FATHER (she was 7) and waved him through for family boarding (when my daughter and I started to board with family boarding, while my son hung back with his grandma, the gate agent said, "Dad can go too"). We checked in at the resort and they thought he was an adult, an adult man in line for Space Mountain tried to start a fight with him (that was scary!), when we were leaving and we dropped our luggage off at the window on our last day, the cast member questioned him about his age, then looked at me and reminded me that anyone over 18 had to show ID.
