How old am I???

Yesterday I stopped at Publix to buy a Lottery ticket ($265M payout - why not try!). I went up to the Lottery register and asked for a "quick pick" Mega Millions ticket, they lady around 45 yrs old) asked to see my ID. I told her "Bless your soul". I handed her my license and told her "I am 38 years old" . The lady said, "I can't believe I was 20 years off on my estimate. You look very young." I know this made my day! It might have even made my year! I guess if I win the lottery it would top it!
