Joined by BBC Brazil reporter Camilla Mota, presenter Claudia Hammond discusses new research from the U.S. that has found that people who have had a vaccine against shingles seem to be aging more slowly.

We hear from James Tibenderana, Chief Executive of Malaria Consortium about research from Brazil that shows that as deforestation expands, mosquitoes are increasingly using humans as a blood source instead of wildlife. What does this mean for the spread of mosquito-borne diseases?

Plus, why does Brazil have a particularly high number of supercentenarians? And could swearing make you stronger?
