Arm injury 2020

see also: my chronic health issues
I have an arm injury and can't use computer very much.
I am writing using Microsoft voice control.
== HISTORY ==
This health problem started a long time ago.  At some point in university, my right hand got worn out from using the computer too much.
== Technology ==
i was using microsoft voice control [and an extension for google chrome] for a while. now i'm mostly recovered [though i had to resort to speach-to-text last year again during a course i was taking in the spring, that required excessive notes]. i do have trackball mice [mouses?] for my computer. one for each hand. Logitch MX ERGO for the right, elecom ex-g something for the left [i luckily have rechargeable AA batteries for that one]. They did take some getting used to, thumb muscles weren't as developed, but now they seem fine.
