At 104, David Goodall believes he's ready to die.
The Australian scientist is so prepared, in fact, that's he's left for Switzerland, where he will be allowed to legally end his own life through assisted suicide.
Goodall spoke to reporters from France Monday as he neared his final destination, according to APTN.
"I am glad to arrive," he said from a wheelchair. "The message I would like to send is: Once one passes the age of 50 or 60, one should be free to decide for oneself, whether one wants to go on living or not."
Goodall wants his decision to send a message to legislators who he hopes will one day legalize assisted suicide in places like Australia.
Goodall reiterated his frustration about not being as free or as mobile in his later years as he once was.
He was expected to meet with a doctor Tuesday and will hold a news conference Wednesday.
Goodall acknowledged he was "a bit sorry to say goodbye to my family in Bordeaux, but that's the way it was."
Switzerland is one of only two countries, along with Colombia, that allows foreigners to enter the country for assisted suicide.
