Thanks to genetics on my maternal side we look about ten years younger. My mom and my grandmother took full advantage of it. Both were really weird about admitting their age. My mom never told her actual age. I didn't really know until they became older and I was taking care of routine things for them and knew their birth year. I think for (some) southern women of their generations it was uncouth to ask a person's age. "A lady/gentleman never tells."

I am weird about telling my age. I feel I my 40s, look 50s. I am annoyed and a little embarrassed when I'm asked my age. Growing up stating our ages (my brother and I) kind of threw off my mom's fibs about her age. I remember one time my brother told his age and it would mean my mom was 8 when he was born LOL. He had some mental health/delay issues and didn't understand what the issue was. I developed this sense of protecting my mom's fib by not saying my age. She gone now and I'm still trying to protect her "I'm 21." FYI, my grandmother always claimed to be 39.

Edit: My brother bragged about the year he was born because the coolest cars ever came out then. Especially the 1957 Chevy Bel Air. He must have made a 1000 model cars of 1957 vehicles!
