Seriously. Spending 5+ hrs a day on the internet... I've browsed all of menshealth.com already..... List'em guys.
Have you tried memorizing the information on lipsum.org? I give you an extra plus if you can recite it backwards.
That's pretty much what one of my friends does. He spends a crapload of time on Wikipedia reading up on pretty much anything you can think of. As a result, he absorbs so much random (and a lot of times, useless) knowledge it's really ridiculous. Usually the knowledge comes in handy when he watches Jeopardy and can answer pretty much every question they throw out there.
