The pill that takes drivers' temperature

Mark Webber meets Dr Simon Sostaric to talk about the pill that drivers take to measure their core temperature during hot Formula 1 races.

The former Red Bull racer says the pill is a welcome change from the alternative method of taking a person's core temperature - by using a rectal thermometer.

Tune in to BBC Sport's live coverage of the Malaysian Grand Prix on Saturday, where Webber will explain in more detail how F1 drivers are medically prepared to race in extreme heat.
