Robert Llewellyn settles into the judge's chair for Level Up Human live from Cheltenham Science Festival. Simon Watt arbitrates as Dr. Kathryn Harkup, Ben Garrod and the studio audience vie for Robert's attention with ideas for improved humans. Ben Garrod explains how to air-taste when you have no sense of smell and we set Kathryn Harkup the task of working out how much would be a fatal dose of marzipan.
