Beyond your personal life space preparations -- build out your literal social network.

Who do you know who is old and frail and might need looking in on? Who do you know who has very young children? Who do you know who is good at cooking? Who might need food? Who can coordinate getting it to them? Who do you know who has a big enough house to host a warm potluck meal over the winter every week or so? Do you have enough people to rotate houses?

Look for what in the US is sometimes called a mutual aid group. If you don't have one: pick two friends, make one.
