I will cope, I always do. I do not say that in any boastful manner, but through my life; long weeks in hospital far from home as a child, boarding school, being married to someone who was in the offshore oil industry as a marine surveyor, almost from the start when HSE was minimal, ditto construction methods and journeys from supply boat to platform was by bosun's chair, not helicopter. Periods away from home frequent and uncertain and in foreign countries, no-one would want to be visiting, through several 'I do not want to worry you, Monica, but..... phone calls, includng being trapped under water in a mini-sub for 24 hours. I have managed, I didn't have a choice. It will be the same if he predeceases me.
But I am worried about what will happen to DH if I go first. He is not as resilient as he is.
DD and I have hatched a plan and we are keeping a constant eye on a particular road in her town, which is freehold owned houses and flats, but within some kind of charitable trust. All this dates back to the 1930s
