Testosterone

Testosterone
Male hormones, particularly testosterone, are the
aggression hormones that cause men to hunt and kill
prey. Testosterone is largely responsible for human
survival, as it drove men to catch food and fight off
attackers. It is also the hormone that makes men's
beards grow, causes baldness, deepens voices and
improves spatial ability. Bass baritones have been
shown to enjoy more than double the number of ejaculations
in a week than tenors, and most people given a
course of testosterone have less difficulty reading maps
and street directories. Interestingly, left-handedness and
asthma have also been linked to testosterone and it is
now known that men who smoke or drink excessively
have reduced levels in their blood.
The downside of testosterone for modern males is
that unless it is allowed to vent itself in a physical
outlet, it may create aggression and can cause antisocial
problems. As testosterone surges through their
bodies, boys aged between 12 and 17 enter the highest
male crime bracket. Give a passive man testosterone
and it will fire him up and he'll become more assertive
and self-reliant. The same dosage given to a woman can
same degree of chemical effect as for a man. His brain
is pre-wired to react to testosterone while a woman's is
not. The reason for this is still uncertain, but it is
obviously related to spatial ability.
Women should watch out for lefthanded,
bald, bearded accountants
with baritone voices who read
maps and sneeze at the same time.
As men reach their 50s and 60s, testosterone decreases
and they become less aggressive and more nurturing.
For women, the reverse happens. After menopause,
oestrogen levels decrease giving them a bigger ratio of
testosterone to oestrogen. This is why women
aged 45-50 suddenly become more assertive and
more self-reliant. The downside is that these women
are more likely to grow facial hair and suffer stress
