All of these people.
Today is my 43rd birthday. This might be the last time that both of the major parties' Presidential candidates are older than me. I think that my 7 year old now doubts that there is anyone older than me. Our conversation this morning:
Him: Happy Birthday!
Me: Thank you!
Him: How old are you?
Him: WHAT? What kind of age is that?
Him: Mommy, what's 43 minus 7?
Him: WHAT? You're 36 years older than me? That's a lot!
Me: (nothing. seriously, how do you respond to that?)
