Why is it inadvisable - or dangerous - to allow victims of electrical torture
to take fluids until many hours after the ordeal?

. After electrical torture the body retains some of the electrical impulses and as most fluids are conductors of electricity it is like adding fuel to a fire.

What are the origins of the terms left wing and right wing?

. For thousands of years in Western culture 'right' has stood for the status quo and 'left' for the opposition. It is interesting that the Latin word for left is sinister, which to us means evil, and the Latin for right, dexter, has given rise to positive meanings such as 'dexterity'.

The Romans apparently believed that the human soul resided in the heels - the good side in the right heel, the bad in the left. But from where these ideas of right being 'good' and left being 'bad' originated, I do not know.

Is it true that unleaded petrol is less efficient and therefore worse for the environment than
leaded in terms of the amount of carbon monoxide and sulphur dioxide produced?

. No. In a car with an engine that's been properly tuned to run on unleaded petrol, the latter is no less efficient than leaded fuel.

What's more, unleaded petrol should be used with a catalytic converter as this considerably reduces emissions of the gases which affect local air quality. These are hydrocarbons, nitrogen oxide and carbon monoxide.

To give you an idea of the scale, emissions of carbon monoxide are eight times greater and emissions of nitrogen oxide are about 12 times greater if a catalytic converter has not been fitted.

As regards emissions of sulphur dioxide, these are minimal as the sulphur content of petrol is very low.
