Robynne and Steven, I have 2 windows 7 desktop computers that run just fine. 1 I use for both genealogy, mostly for my offline work, and my Ham Radio, digital modes and logging, and the other was given to me because it "no longer worked". A simple monitor replacement and cleaning the viruses from the hard drive fixed it but I have no real use for it. My main go to machine is a Windows 10 netbook, originally Windows 8, with a 1 T external hard drive. The one replaced was also a Windows 10 machine, also originally Windows 8, but she wanted to bet a new one and give the old one to the youngest granddaughter who is always trying to help us out. I also have two android smartphones and an android tablet, but I find them too hard to use on WikiTree.
As for my health, I do have some nerve damage due to a different problem, my B12 is fine. They want me to lose weight, cut down on the caffeine, cut back on salt, and cut back on my sugar intake. Also reduce my intake of bread and pasta but to increase my intake of calcium rich foods and spent less time sitting around, for both weight loss and joint problems. As I said, a total lifestyle change.
