2010 - 27: How Young is Too Young?

How young is too young... Should parents just say no to kids who want to do something so extreme and dangerous as climbing Mt. Everest, bullfighting or sailing solo around the world? Is a seven-year-old too young to hate? Is a 10-year-old plagued with psychiatric disorders too young to use medical marijuana?
