The greatest killers The, greatest, killers

Alcohol and cigarettes are the two great-
est killers in the world. Hundreds of thou-
sands of people have died because of these
two social evils. As a result, some govern-
ments are trying to control the use of these
drugs. For example, in many countries, the
legal age for drinking has been raised from
eighteen to twenty-one. Some countries
have even banned smoking in public places.
People can help each other live longer by
simply discouraging these bad habits.
