In a little more detail...

I am a retired [Medical] former Computer Network Administrator having had a career of nearly 20-years duration. Due to my medical condition, I am homebound, wheelchair/wheeled-walker-with-seat and oxygen-dependent. Travel outside of my home location is not presently feasible for me due to physical and medical monitoring considerations and limitations. I communicate with the outside world overwhelmingly through my home computers, all of which run GNU-Linux Operating Systems only, especially Ubuntu/Kubuntu.
