Nineteen

It's also how old I wish I were. Just kidding. Okay, I'm not.

It's how old Josh will be this year.

It's how old John and I were when we got engaged.

It was a favorite number of my early high school best friend Tina. How do you come up with that?

It's obviously the first two numbers of the past century. Does 1999 sound long ago now? Yes.

According to Wikipedia, 19 is the 8th smallest prime number.

19 and the Pentagon - The number nineteen also plays a unique role in the measure of the pentagon... the diagonal of the pentagon has the remarkable property of being the geometric mean between the diameters of the circumscribing circle and the height of the pentagon. These numerical relationships which approach those of the Pharaonic canon of 18 and 19, are as follows:
diameter/diagonal=20/19.021=diagonal/height=19.021/18.092=1.051 (yeah, like that makes sense to us normal folk - just thought I'd throw that in)

Matthew 19:19 says, "honor your mother and father and love your neighbor as yourself". (I choose Matthew because it's one of my favorites)

Nineteen is also how many pounds I've lost since mid January.

Doesn't feel like it, but I'm going to believe my scale.
