Human
In general, humans can survive for two to eight weeks without food, depending on stored body fat. Survival without water is usually limited to three or four days. About 36 million humans die every year from causes directly or indirectly related to starvation. Childhood malnutrition is also common and contributes to the global burden of disease. However global food distribution is not even, and obesity among some human populations has increased rapidly, leading to health complications and increased mortality in some developed, and a few developing countries. Worldwide over one billion people are obese, while in the United States 35% of people are obese, leading to this being described as an "obesity epidemic." Obesity is caused by consuming more calories than are expended, so excessive weight gain is usually caused by an energy-dense diet.
Inhumans
Even without using the Terrigen Mist, the Kree modifications, combined with centuries of selective breeding, have given all Inhumans certain advantages. Their average lifespan is 150 years and an Inhuman in good physical condition possesses strength, reaction time, speed, and endurance greater than the finest of human athletes. Karnak and other normal Inhumans who are in excellent physical shape can lift one ton and are physically slightly superior to the peak of normal human physical achievement. Exposure to the Terrigen Mist can both enhance and in some cases reduce these physical capabilities. Most Inhumans are used to living in a pollution-free, germ-free environment and have difficulty tolerating Earth's current level of air and water pollution for any length of time.
