Yes, very moving.
Dignitas is by the way not the only Charity organisation that organise assisted suicide in Switzerland.
What was not discussed, and should have been- is that his wife and two friends accompanying him would probably be later arrested for assisting someone seeking assisted dying- as several spouses have in past few years. None of them were actually charged in the end. but the stress caused and accusations, were huge. Many people in the past had to go alone, for fear of their spouse, close relative or friend being arrested and accused.
The other one not really discussed, but only touched upon- is that people seeking an assisted death have to do so far too early often- for fear they will not be fit enough to cope with the travel, or lose the ability to take the potion themselves, or not be compos mentis enough to demonstrate that NO coercion was exercised, and that they clearly understand the definite nature of the act on the day.
It is time the Law was changed in the UK, so that people can choose to die at home, and not have to travel abroad to do so (and have the means to do that).
