Australian scientist David Goodall arrives in a wheelchair to hold a press conference on May 9 2018, on the eve of his assisted suicide in Basel. - 104-year-old Australian scientist David Goodall, resentful that he was forced overseas to die, is set to address the media in Switzerland on May 9, 2018, a day before he is due to end his life. He does not have a terminal illness but says his quality of life has deteriorated and that he wants to die. He was barred from seeking help to end his life in Australia, so he was forced to travel to Switzerland.
