Kissing To Burn Calories

In the 'human interest' category of The Australian comes this article talking about a new attempt to break the world kissing record.

Since a kissing couple also burns about four calories per minute, the Swedish pair should burn at least 7436 calories if they want to break the world record.

That must be some seriously energetic kissing as the American College of Sports Medicine (ACSM) lists these other activities that burn 4 calories per minute:

• Weight Lifting: general
  
• Frisbee
  
• Volleyball: non-competitive, general play

Maybe I'm just jealous.
