Why can't we Tickle Ourselves?

21 May 2010
Presented by Chris Smith, Sue Marchant.

Why can't we tickle ourselves? Is deafness down to our genes? Can diabetes cause Eczema? How does deodorant prevent body odour? We take on these questions in this week's show as well as reveal if botox can be used as a medicine, why some people don't feel pain and whether it's possible to wake up with a new accent. Plus we investigate if bacteria could be used to clean the oil spill in the gulf of Mexico!
