Altitude has multiple uses depending on the context in which it is used (aviation, geometry, geographical survey, sport, and more). As a general definition, altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The reference datum also often varies according to the context.

The higher you go above sea level, the less oxygen there is to breathe. When you reach elevations above 2,000 metres (6,500 feet), your body doesn't always adjust quickly enough to the decrease in oxygen. This can lead to altitude sickness, which is actually a group of potentially life-threatening ailments.
