One can be an out-going, sociable person even if they spend a lot of time on their computers. There is no exuse to stay online and be lazy unless one has a lot of work to do on it and therefore is, more or less, restricted from going outside and doing things, for the sake of their job.
Despite that some people are on their PCs and the interweb all day without the need to be, just because they hate being outdoors or cannot be bothered. I suppose if that is what they wish to do then that is fine, but it is unhealthy and they should still go out every once in while.
I do both things so that makes me greater.
