And this is why you should stock up on food and water. And tools :)

If your lucky enough to know that

Nah you should always do that , you never know when you might need it.
If you get sick you be happy if you do not need to go to a store. If the weather is bad its nice to be able to stay at home. And having tools to fix things is cheaper then having to replace them , or pay someone to do it fore you.
