Epidemiology and Physical Activity: Impact on Health
Epidemiology: Understanding Disease Patterns
Epidemiology is the science that investigates and quantifies the various factors determining the occurrence and patterns of disease within a particular group or community. It seeks to generalize this information to a larger population to better understand, modify, or control the pattern of diseases or health problems (McArdle, Katch, & Katch, 1998).

Triangle of Life: Earthquake Safety
When buildings collapse, the weight of the roof often falls on objects or furniture inside, crushing them. However, a void is often created next to these objects. This space is known as the “Triangle of Life.” The larger, heavier, and stronger the object, the less it will be compacted. The less the object compacts under the weight, the greater the gap or hole beside it, and the greater the chance that a person using this void will not be injured.
