The top of my list for things people forget is physical fitness and strength training.
Even with all of the extra manual work to do there will be down time and long periods of it.
Books
Board Games
Cards
Arts and Crafts (papper, pencil, pens and crayons have many uses.)
Not a bad idea to have natural products on hand that fight infections...Grapefruit Seed Extract has many uses. It is a nutribiotic that can be used to fight an abundance of infections. Also Oil of Oregeno and Live Manuka Honey. Black Elderberry is good for bacterial and viral infections.
