You can. Ever been in a quiet room, or trying to get to sleep. You can
quite often hear it then. Or after hard exercise, the blood is thumping
round the system. You should be able to hear that.

Most of the time you won't hear it because you are used to it, and shut it
out.

I find it interesting that we can hear a pin drop across the room, when we
can't hear the thumping and swooshing that's going on inside our heads at
the same time.

I've heard of selective hearing, but hearing something that's softer than
our own internal noise is ridiculous! 8#)

Could you qualify to join Mensa, the international society for high-IQ
people? The only requirement for qualification is to score in the top two
per cent on a standard intelligence test. Members include people who never
finished high school and those with advanced degrees.

See if you're Mensa material. Feel free to use paper and pencil. A genius
at work rarely does everything in his head. Time yourself. There are bonus
points for finishing in less than 25 minutes.

Subject: Don't believe everything you hear.

Don't Believe Everything You Hear
by Alfie Kohn


"You know what they say ..." is one of the most misused phrases in our
language. Hundreds of proverbs have become accepted as folk wisdom, but
many are dead worng. Here's a sampling of popular beliefs.



1. You shouldn't swim for an hour after eating.
===================================================

This bit of folk wisdom was prevalent half a century ago when the US Red
Cross published a life-saving manual claiming that stomach cramps and
possible death awaited foolhardy swimmers who went stright from table to
pool.

But in 1961, exercise physiologist Arthur Steinhaus reported that the very
idea of 'stomach cramps' was questionable. "Many athletes report swimming
long distances regularly in training almost directly after eating," he said.
Steinhaus quoted a prominent physical educator as saying, "I have never seen
a case of so-called stomach cramps, although I have observed hundreds of
thousands of persons swimming immediately after eating."


2. The more you cut your hair, the faster it grows.
=======================================================

When the hairs start to grow back, they may feel coarser because they're
short and all of the same length, but the speed of growth doesn't vary.


3. Couples should beware the seven-year itch.
=================================================

It's not easy to agree on what counts as evidence of an itch. But if you
look at divorce, the answer is clear: There is no such thing as a
seven-year itch. In America, about two per cent of married couples divorce
during the first year, four per cent of those remaining split up the
following year, and roughly five per cent of surviving marriages end in each
of the next three years. After that, the divorce rate drops off.


4. Carrots are good for your eyes.
======================================

Carrots contain beta-carotene, which your body turns into vitamin A. Since
it's needed by your retinas, a complete deprivation of this vitamin would
cause night blindness. But the body has immense reserves of beta-carotene
stored in the liver, easily replenished from a variety of foods. There is
no real danger of running low, at least for people in industrialised
countries. Practically speaking, then, eating carrots will not benefit your
vision.


5. Reading in the dark will ruin your eyes.
===============================================

Tell your mother she was wrong. As the US Academy of Ophthalmology puts it:
"Reading in dim light can no more harm the eyes than taking a photograph in
dim light can harm the camera."


6. Spicy food is bad for the stomach.
=========================================

David Graham, a gastroenterologist, wanted to record what happens to the
stomach lining when people eat spicy foods. Dr Graham and his colleagues
fed healthy subjects a bland meal, a bland meal with six aspirins, a
pepperoni pizza or a spicy Mexican dinner.

The next morning, the researchers used a video endoscope (a fibre-optic tube
that is swallowed) to inspect the stomach lining of each subject. The
people who'd taken aspirin developed small pits in the protective lining of
their stomachs, but no-one else did. Even munching enchiladas with hot
chillis for both lunch and dinner caused no damage.

Of course, Graham studied only healthy people. Surely people suffering from
duodenal ulcers would do better on a bland diet, right? Not decessarily.
In 1984, some gastroenterologists in India sprinkled three grams of chilli
powder on the food of 25 ulcer patients every day, while another 25 went
without this staple of Indial cuisine. After four weeks, the chili eaters'
stomach linings were unaffected, and their unlcers healed at the same rate
as those of the patients condemned to a bland menu.


7. You can catch a cold from being chilled.
===============================================

More people come down with colds during winter than in summer, but that
doesn't mean lower temperatures are responsible. The *only* way to catch a
cold is to be exposed to one of the relevant viruses. The sole effect cold
weather might have is to bring people closer together for longer periods,
which increases our odds of infecting one another.

Yes, they're both right. That generally accounts for breezes (sea breezes)
and constant velocity winds.

Gusts on the other hand a caused by eddies. Okay, think of the Low we see on
the weather charts. It goes clockwise (a cyclone). As it turns, it has a
sort of friction around the edges. This friction causes some of the air to
twist and turn in all sorts of directions....like the slip stream behind a
truck. This slip stream buffets you around, like gusts.

There's also a few other types of wind, generated in other ways, but you'd
fall asleep if I went on,....and on.....and on. Yeh, I guess you know what I
mean! :>

Any help Aimee??
