When I started getting called Sir by beautiful young ladies I knew I was past the point of no return as far as age. 
Being called "Sir" used to make me cringe. My dad was a Marine, so people calling me "Sir!" made me think he was walking up behind me - and he's been dead 20 years! So I'd tell people to cut it out.
But with the grey crawling up my temples and wrinkles getting deeper I realize I am a "Sir" and just accept it. And I don't mind the title if it gets me the senior citizen discount! I'm such a bad person!
