As 5G mobile technology rolls out, some are concerned about potential health risks. Dr Erica Mallery-Blythe has studied the effects of radiation on human health, and tells us there is very little research into the impact of 5G's short wavelength radiation on human biology. Mark Allera is chief executive of mobile carrier EE, one of the first to roll out the technology, and is convinced the new service is safe. Meanwhile Steve Novella, assistant professor of neurology at Yale likens 5G radiation to the electromagnetic field of the sun, and points out we've been exposed to that for millennia. Also in the programme, Zimbabwe has banned the use of all foreign currencies to pave the way for a new Zimbabwean dollar. Our correspondent in Harare discusses whether it is a recipe for more economic chaos and hyperinflation. Plus our regular workplace commentator Stephanie Hare shares her tips on how best to handle public speaking for work.
