This is actually a good question.
I have looked at a computer display screen or TV almost every day for the last fifty years. There are periods when i do not, out in the unconnected wilderness for a month or so ... but not often enuf.
I do not feel need when i am disconnected as in addiction, but i must admit that for various reasons i must connect up at least once every couple months for a few days. I suppose i could go unconnected for a year or two, but thats because i am lucky, with reliable friends and legal help whom i could trust with powers of attorney if it came to it.
Not everyone is as fortunate as i, constant internet seems to be a requirement for life in this new, strange and terrible world.
