It's the date on the Earth Gregorian calendar on which my birthday occurs.
I am, at this moment, just very slightly over 42 Earth years, or 397,339,800,914,623 light-kilometers, old.
Went out to breakfast on my own, dropped some sharps off at waste transfer, then came home and played Oxygen Not Included for a bit. This afternoon, Loree and I got our hair redone, then the household went to Scott's for dinner. I'm a bit drunk, and am about to partake of some of Loree's homemade tincture.
Back to work tomorrow. ::P
