However, "although not as critical as going without water, missing even a few meals can cause a host of undesirable complications," such as lethargy, confusion and disorientation, poor judgment, a weakened immune system and the "inability to maintain body temperature which can lead to hypothermia, heat exhaustion and heat stroke." Much like studies done on surviving without water, exactly how long a person can go without food varies tremendously, yet it is dependent on several important factors, such as a person's overall state of health, the amount of muscle on the body which is "broken down by a starving body and used for both fuel and nutrients," the amount of body fat (an overweight person will normally survive longer than a thin or underweight person), a person's metabolism and the temperature of the environment in which a person finds himself; that is, a cold environment expends additional calories to stay warm, as does a hot environment to stay cool ("How Long Can You Live," Internet).
The following examples shed more light on how long a person can survive...
For instance, prisoners of war have been known to live without food for almost forty days; an obese person can survive up to twenty-five weeks or more without eating, and Mahatma Ghandi, the great Indian statesman and protester, "survived a three-week fast in his 70's ("How Long Can You Live," Internet). Thus, surviving without food and water is dependent on many factors but obviously the human body can only function so well and for so long with the proper amounts of water and food.

Water Awareness and Education for Sustainable Watershed Management Today, the human society continuously deals with the issue of limited resources, as compared to an extensively growing amount of needs. Among these limited resources, water is vital, not only because mankind cannot survive without it, but also because it is essential to producing so many other secondary items, including food and clothing. At the same time, water and watersheds are an essential
While on one hand, the Nile gets the highest discharge from rainfall on the highlands of Ethiopia and upland plateau of East Africa, located well outside the Middle East region; on the other hand, discharge points of the other two rivers, Euphrates and Tigris, are positioned well within the Middle East region, prevailing mostly in Turkey, Syria along with Iraq. In other areas, recurrent river systems are restricted to
Water: The Only Liquid the Body Needs To live a fully healthy and functional life, water is indispensible. From the point in history when primitive species moved from the oceans to land, a major factor of survival has continually been stopping dehydration. The important adaptations that enable this are present in almost all species of animals, including man. Water makes up varying percentages of the body weight of humans from 75%
Survive With No Internet The internet is a home to millions of people worldwide. The internet is a platform that completely changed how people communicate and go about their business. Currently, there are 2,405 million internet users all around the world, out of a population of 7 billion. This means that for every 100 inhabitants an average of 35 people are internet users. Since almost half of the population depends
Energy moves between producers and consumers/decomposers, and the nutrients from soil or air (minerals, etc.) move into the producers and the consumers. All are linked together, regardless of the biome, but food levels have tropic levels and positions. This starts with a basal species that feeds on no other living creature, then moves up to where something consumes something else in order to survive: (Yellow line is transfer of energy;
Given water scarcity, the high costs of desalinisation and other unconventional methods of supplying water, and the pollution of surface and ground waters, Israel sought other natural supplies of water from the Litani" (Dolatyar, 2002).
