I'm 41.
-I don't feel like "my generation will change the world!" anymore.
-I used to feel like Batman. Like I could jump off the roof of my house and be okay. Now, I feel like I shouldn't skip a step when I'm using the stairs.
-I was home by myself the other day. Didn't even feel like masturbating. Not once.
-I used to think that, if I didn't go to sleep, tomorrow wouldn't come. Now, I go to sleep at a reasonable hour.
-I spend a lot of time thinking back to my childhood. A lot of people I knew have passed away.
-I can't just eat everything I see. I have to have some common sense or I could gain weight.
-I don't care about having the coolest clothes or the nicest car. I don't feel like I have to prove how great I am to other people.
-20 year olds scare me. Their hair styles, music, and lack of respect make me nervous.
Aside from that, I feel great. I don't really feel old at all.
