Using Glide Ratio to Stimulate the Hypothalamus & the Adrenal & Pituitary Glands

An extreme sport - Wingsuit Proximity Flying - produces large quantities of Endorphins and Epinephrine (adrenalin). Because the glide ratio of the suit closely matches the terrain gradient over which they fly, there is little margin for error.  The sport has now overtaken cave diving and drag boat racing in terms of death ratio; it's the World's Most Dangerous Sport.

These are skydivers with wingsuits. They have jumped from a plane, and are in danger only because of their closeness to each other and possible parachute malfunction. Nice views.

The wingsuit flyers above are travelling in a forward direction 2.5 meters, for every meter falling to the earth. This is the glide ratio, 2.5:1. Contrast a glider, with a glide ratio of 50:1. Wingsuits are not "good" flying contraptions.

If a person dives off a cliff edge on the top of a mountain, the vertical fall quickly imbues the person with enough velocity so that a wingsuit can start translating the fall into lateral movement. Without the suit, the parachute obviously has to be pulled to prevent a nasty accident - this is known as base jumping. With lateral movement, the wingsuit flyer can continue to plummet, but can closely follow the mountain's terrain below, as long as it's gradient is about the same as the wingsuit's glide ratio. This is wingsuit proximityExhilarating as sky-diving and bog-standard base jumping is, wingsuit proximity flying brings the adrenaline rush to extreme levels.
