David Goodall does not have a terminal illness but says his quality of life has drastically deteriorated. Aged 104, his is Australia's oldest scientist. The eminent botanist secured a fast-track appointment with assisted dying agency Life Circle in Basel in Switzerland. He got on a plane in Perth late Wednesday surrounded by friends and family saying their final goodbyes, including a heartfelt farewell from his grandson (pictured). Dr Goodall was born in London in 1914, and came to Australia in 1948, taking up a lecturing position at the University of Melbourne (inset).
