It's funny that you ask this now. I'm 63, last night I was meeting a guy for a first date. I walked in the place and didn't see him and went over to sit. I was looking at all the men at the bar and was thinking about how many elderly men were hanging out there. Then it hit me, they were probably my age. I don't consider myself elderly. I guess its looks and maybe how you feel. My serger teacher just turned 70, she has the gray hair, etc but I don't think of her as elderly. She travels all over this area teaching and she can pick up my heavy serger so much easier than I do. I don't think its a certain age. Like Bob Hope, he was over 100 when he died but I didn't see him as elderly either, he was active from what I know until the end.
