When you're young and healthy and beautiful (and, trust me, your face will NEVER be more attractive than it is TODAY), you don't appreciate too many things in life. You're happy to buy new clothes or go out with friends in hopes of meeting someone cute. You freak out about a pimple on your cheek or the fact that you can't afford a new car. You spend way too much time worrying about what color napkins to have at your wedding. You think diseases and violence and big troubles only happen to other people, not you.
When you get older, you start not looking so great, but you get smarter and wiser and more knowing. You might wish you could go back to high school or college knowing what you know now. What exactly would you do differently the second time around?
What's the lesson we can take away from this? I wish I knew.
