made to realize in some vivid way how much they needed it
Certain it is that more people would practise hygiene if they could be
made to realize in some vivid way how much they needed it. Few persons,
even when they read and accept the statistics on the subject, really
have a picture of the imperative need of hygiene as an integral part of
every human life. It is not brought home to them how widespread is
illness, how numerous are preventable deaths, how many are the
tendencies toward individual and racial deterioration.
