Dogs really can be man’s best friend. They can transform, and in some cases save, their owner’s life. As pets they bring joy and company but many dogs play an important diagnostic or assistance role.
They are being trained to diagnose cancer and to warn people of an impending hypoglycaemic attack or epileptic seizure. Dogs help people with disabilities, and are also being used to help autistic children.

A parachute is a device used to slow the motion of an object through an atmosphere by creating drag (or in the case of ram-air parachutes, aerodynamic lift). Parachutes are usually made out of light, strong cloth, originally silk, now most commonly nylon. Parachutes often take the shape of a dome, but shapes may vary including some taking the shape of an inverted dome. Depending on the situation, parachutes are used with a variety of loads, including people, food, equipment, space capsules, and bombs.
