Yes. Hopefully euthanasia will be a thing should I reach the decrepit stage. One last party (perhaps with a bit of morphine), followed by drifting to an infinite sleep... sounds fairly dignified.
On top of that, this is also dangerous from a social perspective where people could get a feeling that they are supposed to go once there is nothing they can contribute to society anymore.
We should rather focus on allowing making "regular" dying more dignified rather than promoting euthanasia.
I have seen a few old people live beyond their time and wait for death though. It is quite harsh and undignified. "I am just so tired and I want to go."
