Can you work on computer more than 10 hrs?

Yes I can do this. I have done it over the week ends when it was raining and nothing else to do. There were days when I did not do anything but sit at my computer playing games and doing paid sites and checking through my emails and being on ebay. But it gets boring after a day or two, I have a life in the outside world, too. Real people are more interesting. and one can make better money in a real job. So sitting a whole day at the computer is something for a winter Sunday or a rainy day for me.

I think I could do it. In fact, I probably did it already last weekend...just not for 10 consecutive hours. I did take a few breaks after a couple of hours to go outside. The weather was nice at that time, so I couldn't really pass up some time to go outside. As much as I like working on the computer, fresh air is good...and it's free as well.

Yes, I can indeed work on my computer for more than 10 hours. I really mean work too, I have jobs and projects that I then work on, but I don't really enjoy doing it. My head and neck start to hurt after a while and I find it's better for me to take a break every couple of hours and do something else that isn't computer related.

Oh yes, I can and do. When there is some new and interesting project I persue, I use the following system: working hard on the issue for two or three hours, then surfing a quarter of an hour, then working hard again, then a little gaming, then working hard, etc. This is in order to keep me awake and also to give my eyes a changing display. The only occasions for leaving my chair are to fetch coffee, sandwiches, chocolate, and ... yes. I can make up to 24 hours, but it has to be something I'm very much interested in. If you think this lifestyle can't be very healthy: I'm very healthy
