Hitting the Century Mark

A while ago, I was wondering about the average age in the house (16.7 years, by the way, with a standard deviation of 15.2 years), when I discovered this curious fact...

Our current ages
Tim: 39
Chris: 37
Zoe: 8
Talia: 8
Aaron: 6
Melina: 2
Sum: 100 years

Of course, this is going to change in about an hour. Happy Birthday, Zoe and Talia!
