Around 1884 a game of cards known as Russian Whist arrived in England and became popular in some quarters. Two families of Leicestershire developed the habit of visiting each other on alternate nights to play the game. There was a rickety old bridge on the way between two houses and neither family felt safe while crossing it.While parting, the visiting family would say: "Thank goodness, it's your bridge tomorrow night."They began to jocularly call the game, Bridge Whist but the name caught and eventually became shortened to Bridge.

The reason is that their leg bones are too thin to support the weight of their bodies. Bats that are grounded drag their bodies along the floor to avoid putting weight on their legs. When they hang downwards from their perch, the weight is taken off their legs and the load is borne effortlessly by stretched muscles and tendons.

Though people have always thought that bats bring bad luck, they are actually mild and affectionate creatures. Bats make high pitch sounds which our ears cannot hear. The bats bounce these sounds, off barriers, off houses, roofs and bell towers. The echoes of these sounds travel back to the bats and tell them what is around them in the dark. This is how they catch their prey!

In a single year, the sun delivers enough energy to meet mankind's
current consumption some 10,000 times over.

Studies in 1990 estimated that of the energy used, 77% was from fossil fuels, 18% from 'renewables' and 5% from nuclear energy.

Overuse of energy resources indirectly leads to pollution, increase of 'greenhouse' gases, the depletion of the ozone layer and exhaustion of natural resources. According to some conservative estimates, oil reserves will last for less than 40 years.

In India, local production constitutes 33% of oil needs, the rest is imported.
