May poll: When are we old?

Well, this is a May poll I don't intend to dance around.

When do you consider someone old?
18 1 (5%)
30 1 (5%)
When you/they forget how old they are 7 (41%)
When they make cookies for neighbor children 1 (5%)
When they buy a sedan 1 (5%)
When they back into parking spots 6 (35%)

Honestly, I live by the motto you are only old when you think it or act like it. But I have to admit backing into parking spots is something that well, I call grandma parking. (Sorry Heather!)
And maybe someday I will have neighbor children to make cookies for... although these days with the peanut allergy scare no one would eat them anyway... even if they weren't peanut cookies.
18? 30? Come on, people... that has to be my mom or dad goofing around with the poll. But if it is not SHAME, SHAME, SHAME. Whoever thinks that age is what makes you old has never met Ryan Livingston's grandpa who can still ski better than most people and he is in his eighties... or Patrick's grandpa who go the the gym and lifts weights daily.
I think that forgetting someones age can happen at any time in life. I forget people ages all the time, and sometimes my own. Actually, right now I can't remember how old Patrick, Catherine, Melissa, Mom, Dad, or Laura are... I guess either I am old or not good with numbers. Sometimes and this has happened ever since I turned 20, I forget my own age and I am off, plus or minus a year. Hey I am in my twenties, is there really any need to be precise? This was a problem when I tutored elementary school kids. Becuase, third grader takes it as a serious offense if you confuse them for a second grader.
