Jo welcomes Professor Adam Hart from the University of Gloucestershire back to the show to bust some health myths on things like detox diets.

There's also the story behind some special needles that played an important role in the eradication of smallpox, which are found at the home of Dr Edward Jenner in Berkeley.

Plus Jo chats to author Sarah Franklin who grew up in the Forest of Dean and moved away – but returned to her Forest roots when she wrote her debut novel.

And Jo’s Festival Flashback is her interview at the 2017 Cheltenham Literature Festival with writer Lois Pryce who motor biked from Alaska to Argentina and also rode solo around Iran.
