Ivan Shamyanok, 90, sweeps inside a pigsty near his house in the village of Tulgovichi, near the exclusion zone around the Chernobyl nuclear reactor, Belarus April 2, 2016. Shamyanok says the secret to a long life is not leaving your birthplace even when it is a Belarusian village poisoned with radioactive fallout from a nuclear disaster. In April 1986, a botched test at a nuclear plant in Chernobyl, Ukraine, sent clouds of smouldering nuclear material across swathes of Europe and forced more than 100,000 people to leave a permanently contaminated "exclusion zone". April 26, 2016 marks the 30th anniversary of the worst nuclear meltdown in history. REUTERS/Vasily Fedosenko SEARCH "EXCLUSION IVAN" FOR THIS STORY. SEARCH "THE WIDER IMAGE" FOR ALL STORIES
