45

 Forty-five. 45. 

Multiples of 45 include 1, 3, 5, 9, 15, and 45. It is half of 90. 

It is the sum of all single-digit numbers: 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 

It is the atomic number of rhodium, the RPM of a type of record, the dialing code (+45) of Denmark, and the 45th president was...

God, we all know that. And he is a nightmare.

And that is my age today. I am 45, but I am also my-contacts-prescription-for-distance-is-so-strong-I-now-need-reading-glasses-for-my-computer years old. I am homeowner-with-means-to-travel years old. I am teaching-twenty-years-now old. 

I am middle aged, with all of the good and wild that comes with. 

Happy Birthday to me!
