Having a stroke is something many of us associate with older people, but that’s not always the case, as we find out, in this week’s interview with a courageous stroke activist who’s been telling staff at UN Geneva how he managed to learn to speak again. In Yemen, the UN migration agency IOM, has issued a warning about the tens of thousands of migrants from Africa who continue to be trafficked, shot or worse; in Geneva, North Korea’s missile tests have prompted strong words at the UN’s top disarmament forum; while 100 days of war in Ukraine have had predict ably awful results for most of the country’s youngsters. Last but not least, we’ll also hear a potentially promising COVID immunity update from the WHO.
