Working with the remarkable English born Shaolin monk, Matthew Ahmet, I was able to recording what was happening in his brain and body as he performed truly astonishing mental and physical feats by harnessing the power of his breath.
In a demonstration for the US TV series Superheroes, for example, he was able to push a Toyota Landcrusier across a car park at Sussex University by means of a spear whose point was place against his unprotected throat.
As he did so I measured changes in his brain activity, heart rate and breathing, watch this video of him performing this apparently impossible feat.
