My friend sold plasma to save up for a PS5 only, so he got juiced a bunch of times over a somewhat brief time. Now, a couple of years later, he still has permanent puncture scars on both arms. I think this can build up scar tissue that makes it harder for nurses to get to your veins in the future (but I could be wrong about that, idk).
When I first returned to Linux several years ago I started with Ubuntu, since it was the only distro I had used. I got confused when I installed Firefox and other apps via apt but instead got snap instead. This (very miniscule) gripe is enough of a reason for me to not recommend Ubuntu to new users anymore.
