67 here and live alone. I am not a "joiner" of things and like my own company best. That goes against the grain I know, since I should be gadding about volunteering for this or that and joining every club under the sun. That's just not me! I have good family and friend connections though, but not every day of the week either!
However, I get out and about every day except Sunday. Walk around 5k sometimes more, sometimes less, and often with a backpack full of groceries or whatever. Fingers crossed, I feel great, never need a nap and sleep well, eat well and so on. Everyone is different.
Back to prep. I live in a three bed semi that only had one bathroom upstairs. Last year I got the house refurbed and fully insulated, new kitchen, bathroom with walk in shower, plus installed a downstairs loo + shower aswell. I don't use the d/s shower, but it's there if I need it in the future. I already live close to everything I need, so that's as much prep as I've done so far! Oh I did will, POA, DNR, all that sort of stuff, and got all paperwork in a folder in case I drop down some day.
If I need a care home so be it. My only stipulation is that my room is on the ground floor with doors to the outside. I can afford something like that, I made provision for it. And I DON'T WORRY about what may or may not happen to me, I've done as much as I can, the rest is in the lap of the gods.
