How Hormones Control Us
In the past, it was thought that hormones only affected
the body and not the brain. We now know that
hormones programme our brains before birth, dictating
our thinking and behaviour. Testosterone in teenage
boys is 15-20 times higher than in teenage girls and the
hormone flow in boys is controlled and regulated by the
brain as the body needs it.
At puberty, testosterone surges through an adolescent
boy's body, giving him a dramatic spurt of growth and
a body ratio of 15% fat and 45% protein. As he turns
into an adolescent, his body physically changes to match
his biological job description as a lean, mean, lunchchasing
machine. Boys are excellent at sport because
their bodies are hormonally constructed for effective
breathing and they have excellent oxygen distribution
via the red blood cells to allow running, jumping and
grappling. Steroids are male hormones that build additional
muscle and give athletes extra 'hunting' abilities
and an unfair advantage over non-steroid takers.
Female hormones have a different effect on teenage
girls. They are not regulated like a boy's hormones but
come in huge waves over a 28-day cycle and can cause
havoc for many girls and women due to the rise and fall
of emotions that go with it. Female hormones change a
girl's body into a ratio of 26% fat and 20% protein,
much to the frustration of females everywhere. The
purpose of the extra fat is to give additional energy for
breastfeeding and is insurance against times when food
may be scarce. Because female hormones fatten the
body, they are used to fatten livestock. Male hormones
reduce fat and build muscle so they're unsuitable for
animal fattening.
