Approximately 17246.25 hours from approximately 8:00 A.M. January 1, 2000 to last night!

Of course I probably forgot a few coffee breaks so feel free to round that number off!

I can honestly say I've never exceeded 24 hours of use in any one day in all the years I've been online.

Other than the time I am in class, I am always online. My only job is writing for people on Warrior so I am always home. I actually bring my computer to class too for in between and in a couple of classes that allow laptops.
