1. Skills, especially medically related. I took classes like Wilderness First Responder, gunshot wounds, CERT, SARTECH, Red Cross classes for professional rescuers (I'm not a pro rescuer). Because of my career, all of that has become just a distant memory. Now I don't even know what I can do. While my previous location put me within striking range of many such classes, my current location has very little. I'm not sure how to review this stuff and regain my skills. I feel like I could start by going over my old textbooks and notes.
Depending upon how old those textbooks are, that might not be a good idea. There have been a TON of changes in medical protocols in the past decade, many diametrically opposite what for decades was "settled" treatment. Just saying...
