I am a pensioner, but I have worked all my life and started using a thunk thunk type manual typewriter.
I progressed to the stand alone wordprocessor which you will have no knowledge of, as it belongs it a museum now. :)
It was a natural progression to the basic early computers which came on the market and required computing skills that just aren't necessary now. One needed to learn and understand dos commands for example.
I really enjoyed it, and in my spare time got qualifications in wordprocessing, computer studies and went on to get an IT teaching certificate.
After I retired from my proper job, I taught other older people how to use computers and the internet at my local college.
I am more or less housebound now, and very hard of hearing, so I help out online where I can.
I am still learning! If you enjoy something, it is very easy to want to learn.
Don't forget that pcs and technology weren't invented overnight - it developed over many years and the first computer is probably around 60 years old. :)
Although it was bigger than a van.
