Man can live without food for about forty days, about three days without water, about eight minutes without air, but only for one second without hope. And Jacob did not lose hope. Even when every cell in his body told him to. He kept going and that is what helped him reach home. Courage is often derived from fear. For Jacob, the fear of never seeing his family again was enough to keep him alive for 4 days without food and water in such harsh conditions.
