In a book called Why We Get Sick: The New Science of
Darwinian Medicine two doctors admire the sophisticated design
of our bodies and ask interesting questions to which many of us
would love to know the answers.
For example, why do we crave the very foods that harm us but
don't particularly like vegetables? Why do we continue eating when
we know our fat reserves are already excessive? Why are we equipped
with insufficient willpower to restrain our desires? And, while our
immune system can fi ght so many disease causing germs, why can it
not leave pollen alone, resulting in allergies? The authors
say:

in the universe took every seventh day off and turned the work over
to bumbling amateurs." (p.5)
