When did you realize you were old?
Me: When I would rather stay in on the weekends than going out.
I remember listening to "Lunchtime with the oldies" on the radio while I was at Ft. Meade, Maryland. I was in my early 20s, and they played a song that I loved in high school. I was pissed about that for days! And that was the first time I realized it was really all downhill from there. My middle daughter freaks out about wrinkles and turning 30! I told her "really? Every wrinkle and grey hair I have has your name on it" I may be old, but I don't care! I'm OK with it. My mom died at 45, she never got to meet her grandchildren or see any of her kids get married or any of that other cool "getting old" stuff. Your age is just a reflection of the number of trips around the sun your have made. Don't let your age define you. I may be 60 and my knees make some odd noises and yes I have a few gray hairs but dammit, I put the time in for it. I earned it! I am happy about it because so many don't get that opportunity. JMHO ( or not so H)
When my desire to not have a hangover or a DUI compelled me to almost always avoid drinking.
Menopause and it’s lovely symptoms.
When I look in the mirror and wonder “How the hell did that happen—and so quickly?”
When having fewer wrinkles and not wanting skin cancer became more important than being tan.
When being comfortable and taking care of my feet and hips outweighs choosing 3-4 inch heels.
Some of the things I notice might be more an effect of maturity as opposed to feeling or being past the middle point.
I'm old? OK, OK, I'm old. I think it was kind of the same thing someone else mentioned below; jumping down from even relatively low heights became daunting, running turned into very cautious loping, climbing ladders is scary, routine things that I didn't much think about doing when I wasn't "old." Then there was the realization a few years back that the little baby girl I used to cradle in my arms was a grown woman with a whole life of her own.
My kids make me feel old a lot but that's normal. One thing that makes me feel old without their influence is singing along to grocery store music. I was in Wal-Mart the other day and heard Anne Murray and I was so excited because I hadn't heard her for so long, I forgot she even existed!
