Shouldn't more of the world's population be committed to a mental institution?

February's National Geographic features Love (say it together now, awwwwhhh) on its cover, with the following quote:

Scientists say that the brain chemistry of infatuation is akin to mental illness — which gives new meaning to "madly in love."

I know some mentally ill people at the moment. It's not a pretty sight. Where's that strait jacket? (thanks B)
