It was a very unstable element until around the 1950's or 60's.

Not true. Gallium- named after France in Latin, does have radioactive isotopes but isn't radioactive intrinsically. As a fun science note- while Scandinavia isn't a country but a group of countries, scandium is also not found in nature in radioactive form. Germanium was discovered before radioactivity was discovered. The other newer "country name" elements were found after- with pulonium being found very shortly after radioactivity was discovered. Americium is used for smoke detectors, medical equipment, and other portable sources of gamma rays. Germanium is used for alloying in transistors, francium is too unstable for practical use but is used for experiments and can decay to a radium isotope used to fight cancer. Scandium is somewhat rare and has positive properties for alloyin with Aluminum.

Do you just read books all day, or what?

I used to read a lot more when I was younger in school. Now I occasionally read books but mostly read e books and technical literature in between when I'm working or doing other stuff or read as part of training and keeping up for work. I have my phone at all times and my job isn't super hands on most of the time, so when I'm waiting for something I can read if there's nothing new and cool on funsub. That or watch movies, lectures, or documentaries.
