thanks, 淘侠, for listening to me.

After replying to your post, I checked with a native speaker about tender age. He did say at "his" tender age is weird. maybe other native speakers use it this way, I don't know, but "tender age" feels more like a collective term (集体名词？general term？）to me. I will check with some other native speakers in the future.
