Most people feel older on their birthday. Not me. I feel older on New Year's Day. Perhaps it's because I wake up a bit under the weather from the previous night's festivities. I look at myself in the bathroom mirror and think, Who's that?!
If you are young and want to know what you're going to look like when you get older, consider how you look with a really bad hangover. You know, the times when it looks like a truck ran over you? Well, that's what you're going to look like in another 30 years, even without a hangover. Even with makeup.
The rest of your body won't fare much better either. You'll go shopping and come home empty-handed because nothing "looks right" anymore. This goes on for a decade, maybe two, until you come to terms with your new old self.
