Survival skills
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
Famine events
During the event, for 30 hours, participants must abstain from eating food, and instead they typically drink water, fruit juices, or other liquids Games, fund raisers, and other events may also take place to help teach and educate the participants and others about world hunger all over the world. It is also a time for education and awareness of world hunger, and an understanding of how people go without food for long periods of time. This, however, does not exclude those unable to fast.
