It happened twice last week.
Someone waited to let me on the elevator first. “Age before beauty” he said. He was obviously younger. I joked with him in protest.
Then, a few days later, a man held a door for me into a building.
“Age before beauty” he said. Although younger, I didn’t perceive a great age difference. (Maybe my perception was off.)
I thanked him, conveyed that his gesture was appreciated although unnecessary, and shared with him that I’m not ready to receive such courtesies.

My birthday was earlier this week.

I still think that I should be opening doors for others.
