they are having more fun than me

Do they mate for life? I would assume no, but I wouldn’t have assumed this title, either!

TIL the common earthworm has more game than me

I found out just a few years ago that many earthworms are invasive species in North America: https://en.m.wikipedia.org/wiki/Invasive_earthworms_of_North_America.

Apparently the last ice age cleared out all the earthworms north of the 49th, and existing native species didn’t migrate back after the glaciers receded, leaving many northern and west-coast forests without earthworms at all.
