It has helped me to watch medical procedures on Youtube prior to having them done on me. For examples: heart radio frequency ablation procedures; mouth bone graph procedure; tooth implant procedure and Foley catheter procedure. Some folks just don’t want to know what happens to them while they are under anesthesia while being operated on. For me I want to know every small detail.
There are numerous Youtube channels dedicated to the sort of wilderness and primitive skills I practice and teach, and I’ve learned a lot of neat tricks from them. EatTheWeeds is one of my favorites. I thought I knew a lot about foraging before watching his videos, but there’s always more to learn.
I just watched several that allegedly explained how to rewire a lamp with a three-way socket. Then I watched my contractor actually do the job. He was clear, precise and used just the right number of words.
I learned that I can only do so many things well and becoming an electrician is not one of them. Now plumbing is a different kettle of fish. The worst that can happen is a flood rather than death.
I’ve looked up hair tutorials on youtube which would be more helpful if I were more ambitious.
I’ve watched crocheting tutorials which have been very helpful when I’m in the middle of a project and don’t know how to do something.
Lately I’ve been watching silkscreen tutorials because I want to put custom designs on shirts.
