emugglsu What she is singing about is not only of age, some people experience so many things more than any average people does, and some even experience 50 years in only few years, so we have to understand experience is not only of age. This song reminds me of my son because he is the one I will pass on my stories to, he is gonna be the one I would climb mountains or swin through the oceans, even though I am only 25 I have been married, abused and raped, but that never stopped me from loving another person, I have had a lot of good times and bad times. This song is about having someone, and we may not have lines in our faces, but those lines may also mean scars that are not visible. She doesn't only refer to people in a specific year span, but all those that want to listen.
No offense, I just want to explain.
