After reading the other posts, I feel like I don't have room to comment at 27. But, over the past year or so I've definitely been having my first real brush with the notion that I'm not in the springtime of my youth anymore. 30 is hurtling towards me faster than I can scream and cry in the opposite direction, which is weird because I just turned 20 last week, or so I thought.
That Simpsons "I Used To Be With It" gag doesn't feel as much like a gag either. Hell, I made this account when I was a junior in high school, and now I see "10y" next to the username and I'm wondering where the hell the time's gone.
One thing I notice now is how my perception of people much older than me has changed. It sounds a bit churlish but when I was younger, the fact that other people lived on a continuum of ages never really clicked. If I met someone who was in their 60s, it would never subconsciously click that that person also lived through their 50s, 40s, 30s, 20s, 10s, etc, just as I'm doing right now. They had evidently just forever been in their 60s.
Now I force myself to try and see people at different points in their lives, and how those periods in their life contributed to who they are as I know them. I mean, hell, I don't feel much different than when I was 20. Now it strikes me that that must be how people in their 30s, 40s, (...) must feel too. Mentally we're no different, though physically we may be; and that's likely how it'll feel to me in the future.
Thankfully I feel as if I'm more aware of my position in the universe than others my age, and I'm trying to prepare myself to age gracefully. I know I'm still quite young and still able to do broad course corrections before I'm sidelined into any one path. I'm trying to take advantage of it to the best of my ability.
