I always get offered the senior discounts at restaurants and stores (over 65! ) even though I am no where near that age. I guess I just look older. How old can I pass for?

No you should not. You would know you were lying and it would lower yourself esteem to know you were cheating.

Are you an AARP member? Is that why you are being offered the discounts? These days almost anyone can join the AARP and avail most of the discounts.

Funny, even when my dad was over 65 he would refuse the discount because he didn't want to be considered old.

The question is, are you okay with cheating people out of money? If you are, you have a lot to think about, the least of which is saving a few bucks on dinner.
