cerned about their defence, if they want to lead a
healthy and peaceful life. They inevitably have to protect
themselves and their possession against criminal acts,
such as theft and murder, as well as against natural dis-
asters, such as accidents, fire, earthquakes and floods.
But this is not the end of the matter. Human beings

much more resilient than the others. Serious measures
must, therefore, be taken to guard against them.
Who, or what then these enemies that keep human
beings under constant threat?
They are bacteria, viruses, and similar microscopic
organisms, which may exist in the water we drink, the
food we eat, the house we live in, and the office where
we work. In essence, they are everywhere.
Most interestingly, in spite of being surrounded by
such a serious threat, we make no effort whatsoever to
protect ourselves against it. This is because there is a
mechanism within our bodies, which undertakes this
task on our behalf, providing the necessary protection
for us, without causing us the slightest disturbance. This
is "The Defence System".
It is one of the most important and amazing systems
operating within our bodies, for it undertakes one of
the most vital missions of life. We may not be aware of
it, but all the elements of the immune system protect
our bodies just like the soldiers of a huge army. The de-
fence cells that protect the human body against invad-
ers, such as bacteria, viruses, and similar
micro-organisms, are equipped with extraordinary abil-
ities. The patterns of intelligence, effort, and sacrifice,
