Interesting question…
Well I can if I have to, and I did have to for a little over a week last year when my computer was in the hospital having surgery. Eeek!
I was ok with it because I knew I had to, so I did other things. But, I did miss it for all the things I do on it…like some of my writing, and especially connecting with others.
I would not like to be without it longer than a week.
