AFTER living for 104 years, Australian scientist David Goodall has voluntarily ended his own life. This is how it happened.

DAVID Goodall, 104, will voluntarily end his life today. He has spent his last hours wandering the gardens in Switzerland.

Goodall said he would have preferred to have died when he lost his driver's license in 1998, adding that the loss of independence at 94 was a big moment in his life.
