Like me, you've probably wasted more of your life sitting on Facebook than you'd like to admit. It's addictive and thrilling and such a complete waste of time, but that's OK because it's harmless, right?

Um, think again.

New reports are showing that Facebook is bad for your health -- in fact, it can raise your risk of cancer! Studies aside, think of it this way: If, say, you took all the time you spent snooping on your ex's profile or playing Facebook Scrabble or incessantly updating your profile and used that time to lift weights, go for a run, do yoga or even cook a healthy meal, think about how fit you'd be right now! It boggles the mind.

I'm not saying you should quit Facebook cold turkey, but you should consider giving up some Facebook time for something a bit more physically healthy. Myself, I refuse to get on the computer until I've gone for a run or at least done some sit-ups, and it works pretty well.
