Q:

What is lifespan?

A:

For people, animals and plants, lifespan refers to the length of life, according to the Oxford Dictionaries. For equipment, machines, appliances and other products, lifespan describes the length of time for which the item is functional.

The phrase "expected lifespan" describes the length of time that the average human lives. As health and science evolves, human lifespans get longer, according to Scientific American. The expected lifespan, or useful life of a product, is one of the factors evaluated by potential buyers. A durable product that lasts longer offers more value than a product that is expensive and has a relatively short lifespan.

    How do people float in water?

    A:

    People float in water by having a lower density than the water surrounding them, according to Scientific American. Because human body fat is less dense than water, people with a higher proportion of body fat float more easily than people with low body fat. Taking a deep breath also decreases body density since air is less dense than water, as discussed by MechLabs.
