In the UK, a significant proportion of children have not only experienced drinking alcohol by the time they are allowed to purchase an alcoholic beverage (i.e. before 18 years of age), but are likely to have been drunk at least once in the last 4 weeks.

A British Thermal Unit (Btu) is a measure of energy content, usually used to describe the energy content of fuels. Because a Btu is so small, energy is usually measured in millions of Btus. 1 Btu = the amount of energy required to increase the temperature of one pound of water (which is equivalent to one pint) by one degree Fahrenheit. This is roughly the heat produced from burning one match. 1,000 Btu = four-fifths of the energy contained in a peanut butter and jelly sandwich. 100,000 Btu = one therm, such as what you would find on your gas bill.
