Do you believe in true love?

In 2004, National Geographic photographer Jodi Cobb set off on any reporter's dream assignment: go find love and capture it on camera. 

"Scientists say that there are three stages of love – lust, romantic obsession, and long-term attachment," said Cobb.

She started with lust (who wouldn't?), and that took her (where else?) to spring break in Cancun.
