The last time for me, was earlier this year by a workman on the scaffolding at work, which was a bit embarrassing as it was also heard by the big boss!

Several years ago Mr F and I went to visit an elderly relation in a home and whilst we were chatting to the matron an elderly lady (80+) went by using a zimmer frame. The matron complimented the lady on her new hair style and Mr F gave her a wolf whistle. You should have seen the change in her, she gave Mr F a saucy smile over her shoulder and positively minced off down the corridor with her zimmer frame. So in response to the question, I don't think you are ever too old.
