Well, okay maybe not 37 reasons. How about 3?
1.) 37 is a nice age to look back and see how far you've come, the things you've accomplished, and all the ways you've become wiser.
2.) 37 is pretty much mid-career for me. 15 years 'til I'm out of the workforce forever.
3.) 37 isn't dead yet.
The end. Whew, that took a lot out of me! I'm not getting any younger, you know.
