We humans need things to live, but we can create these things from our surroundings.

If you wish to live, you need to learn this:

From what is around you now

Make shelter

(shoes, socks, rain gear)

Make fire

(flint & steel, ferocerium, lightet)

Make clean drinkable water

(filter straw, filter bottle)

Make a weapon

(spear, knife, ax)

Carry these items all the time.

If they are not on your person you are dead.
