Different for everyone and circumstances and psychology before the dying process. For example, was the liver disease the result of alcohol,

hepatitis C or what ?

Kaiser Hospital just killed my best friend of 42 years.

I mean you don't wait 3 months from finding a lung tumor to removing it.

I am angry but, he was cool with it. Caught pneumonia and before sinking into a coma, told his doctors he had a good life. I should say he told his murderers he had a good life. It was a one year process.

Death is a personal and intimate event, no one will ever die in the same way that someone else dies. As you have lived so will you die, - and by that I mean that death will be experienced in the same way that you have lived your life according to your beliefs, philosophy and personal outlook upon life.

Genetics doesn't much enter into it, but the processes of socialisation into the society in which an individual lives will be the biggest influence.

I was a social worker for the mental health service for some years and over that time several clients of the service I'd come to know died of suicide, or neglect, or illness. These days I belong to a religious congregation that prays for those who are suffering and are at the point of death. Often someone at the point of death will hold on against all odds so that they can say goodbye to a relative or friend who is journeying to see them. And having seen them they will then die in peace. Death is a mystery.
