eight and thirty
A bit of a stretch to come up with a clever factoid to comemmorate thirty-eight orbits around the sun, but the internet is nothing if not bountiful:
The number 38 was especially prominent in Norse mythology. The number was said to represent unnatural bravery, characteristic of the legendary heroes of Norse sagas. Most legendary sagas were divided into 38 chapters, and the number often recurred throughout stories, with the heroes combating giants or other beasts in groups of 38. The number came to be adopted by the Hardrada clan, and was displayed on their crest in the form of 38 ravens set around 38 outward-facing arrows.
So, happy birthday to me. Perhaps this will be the year I finally slay those pesky frost giants…
