Two 45-year-old twin brothers in Belgium were euthanized by doctors on December 14 because they were going blind.
According to ABC News, the twins were already deaf, and the men decided it was best to be euthanized before going completely blind.
Their doctor said the men were born deaf, and before departing from the world they had a very peaceful and happy goodbye with their family members.
They had a cup of coffee before taking their final steps into the hospital room where they would die.
"They were very happy. It was a relief to see the end of their suffering," said Dr. David Dufour.
"They had a cup of coffee in the hall. It went well and a rich conversation. Then the separation from their parents and brother was very serene and beautiful. At the last there was a little wave of their hands and then they were gone."
Euthanasia is legal in Belgium, where more than 1,000 people legally had doctor-assisted deaths in 2011. Most of these patients had terminal cancer.
The twins are different in that their illness was not terminal. But Belgium law allows doctors to euthanize patients who are "suffering," are mentally sound, and are over 18.
Lawmakers are considering implementing a law that would allow euthanasia to be extended to dementia patients and children whose families gave consent.
