From a “giving tech support” POV, nano is the best editor. Have you ever tried walking a non-techie through editing a config file on the command line, over the phone, no screen share? Nano is your friend. (I swear, this very expensive software I used to support got its sysadmins by picking whoever was absent the day the the client site figured out someone had to do it.)
I’m in a disabilities chat group and we’re often surprised when we’re reminded that “0” is the “normal” level of pain you’re “supposed to have” day to day. Everyone’s baseline is different. Pain sucks. (Unsolicited fact: my back pain got much better after I started physical therapy for it. I’m glad my health insurance covered it. Next round of PT: my knees. Why they be like that? [it’s probably the EDS])
