Whatever happens to us, how ever sensible and organised we are, we should all face up to the fact that are going will cause our children 'pain, angst and worry.'
It is one of the comfortable delusions of our generation of older people that we think we can, if we get the organisation right, reduce our end to a quick disappearance act that causes no-one any problems and everybody else marches on with barely a ripple on the surface of their lives. It won't be like that.
As I said my DF lived a life of complete independence until his last illness at the age of 92; one week feeling unwell at home, 3 days with me and then 2 months in my local hospital until he died. It really couldn't have been easier and less hassle, but the amount of pain angst and worry it caused me was immense and I wouldn't have given up a second of it.
Last week a man went to Dignitas under his own steam to be put down before his illness made him quadriplegic. All done under his own steam, no trouble to his family, everything neatly set up. Have his family returned home given a big sigh and got back to life as normal? Everything I have read suggest that they are distressed, grieving, in pain, and struggling to understand their father's decision and missing him, missing him so much.
The hands over ears and singing la la la attitude has much to be recommended. Better than believing that you have any control over what will happen at the end or control over how your children will react and deal with it.
