I'm just under 30, so I'm starting to get to a point where I'm older than coworkers and there are a lot of adults younger than me now. That is weird to go through. In other ways though I feel like I'm realizing how young I am, I felt so grown up and mature at 20, but I'm realizing now that I gained a lot of perspective in the last decade and I just don't have the same knowledge or experience that my older friends do. Not that younger people aren't smart, and their perspective on things is really interesting, just in a different place.

On a less philosophical note, it does make me feel older when my injuries add up and I get little new health problems.
