Here are my moments:
Taking my glasses off to read stuff up close. If I'm wearing my contacts, I have to hold it WAY out there.
I was gassing up the car with my son one day. He made some comment about how expensive gas was. Then I remembered when I started driving, I could buy a tank of gas, get a soda and a candy bar, pay with a 10 and get change.
Some of the privates in my platoon were born after I went to basic training. One of my PFC's was giving me my road test for the FMTV and I mentioned that I'd served for every president since Regan. His remark: "Holy S#$t sir, how old are you?"
Things are beginning to hurt for no apparent reason.
I was in basic training when the kids that are becoming legal to drink this year were born.
But, 40 is cool. I'm having a good time.
