"Clormium 5 is an odorless, tasteless, and generally harmless industrial by-product that
can enter the water supply. A preliminary study has linked cooking with water
containing clormium 5 to an increased incidence of allergies and skin rashes. Tests of
the drinking water in several areas have revealed the presence of clormium 5. Although
it is possible to remove clormium 5 from water, the costs of routine testing and
purification are higher than many communities can afford. Therefore, in order to prevent
allergies and skin rashes, communities that cannot afford to rid their drinking water of
clormium 5 should replace drinking fountains in public buildings, such as schools and
libraries, with bottled-water coolers."

61) Allergies are an overreaction of the immune system to certain stimuli. One view is
that allergies can develop as the result of childhood exposure to certain irritants, such as
dust or animal dander, while the immune system is not yet mature. Another view is that
exposure to particular bacteria early in childhood actually triggers the proper
development of the immune system, and that limiting exposure to these bacteria through
excessive hygiene can cause children's immune systems to overreact to certain irritants
later on. A new study supports the second view: children who are washed especially
frequently and whose parents clean their homes especially frequently are more likely to
develop allergies than are other children. So in order to reduce the incidence of allergies
in children and adults, parents should not limit children's exposure to irritants or
bacteria.

62) The following appeared in a letter to an editor.
"In many countries, wood is the primary fuel used for heating and cooking, but wood
smoke can cause respiratory and eye problems, and extensive use of wood causes
deforestation, a major environmental problem. In contrast, charcoal, made by partially
burning wood in a controlled process, is a fuel that creates less smoke than wood does.
Moreover, although charcoal costs slightly more than wood, less charcoal is needed to
