It's interesting that for some people, the pursuit of real-life activities is a fair opportunity cost of spending time on a computer (I won't claim I'm not one of them). Has there ever in history been a diversion that is able to keep people inside their homes for months on end?
Why is the computer activity the "diversion" while "real-life activity" the thing diverted from? The computer is only an extension of the human user. It can be used for almost any purpose.
