As the emotional roller coaster of the Euros comes to a close and the summer Olympics begin, James joins Professor Damian Bailey for an experiment to measure the ups and downs of watching sport. We monitor brains, hearts, lungs and hormones to try to out if watching sport is good or bad for us.

But is there an additional risk for sports fans attending the summer Olympics in Paris? As climate change drives the tiger mosquito northwards there are concerns over the potential spread of Dengue in France’s capital. James talks to disease ecologist Dr Jennifer Lord to discover what France are doing to prepare for this mosquito-transmitted virus.

Plus, Professor Peter Openshaw joins James to digest the latest Covid-19 inquiry and what lessons we can learn for the next pandemic. Together, they discuss why we are currently experiencing a summer wave of Covid-19.
