Gd exists

I’m not referring to G-d, but to gadolinium, the rare-earth element whose chemical symbol is Gd. Never did learn enough about those rare-earths in school. Somehow, I’d forgotten that Gd even exists, but was reminded of it today.
Apparently I’m going to get a shot of some Gd compound on Monday when I have a little MRI done on my head (…insert joke here…), as a followup to a hearing test I took this week. No biggie.
