School is having "freedom day" to discuss 9/11

On 9/11/1, thay were just striking a blow toward that goal,
trying to intimidate us. It did not work.

Of course it intimidated you.

Asserting that you're not intimidated means nothing.

Think of the ongoing expense of what they did.
The red alert for every anniversary adds non-productive costs
to the demand side of the economy and of a substantial order.

And they lay that cost on us without even doing anything.
They created the Dep't of Homeland Security, thousands of new
regulations in regard to banking, credit cards, internet and travel.

They intimidated us goodstyle and will continue to do so.

It's so clear by the many posts you two have made in this forum, that you don't care in the least whether or not everyone thinks like you.

Keep telling yourselves that but your hypocrisy shines like a neon sign.

Being careful and being afraid r not the same thing.

Do u feel timid ??

You're just another ******* armchair tough guy.

I'm not claiming to be tough.

But why do your ears pop anyway?

Why do your ears pop in airplanes?
(Lansing State Journal, September 2, 1992)

Question submitted by: Pan Field
Your ears pop in air planes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down.

Some air planes can fly so high they require oxygen masks or a pressurized cabin, so the pilot and passengers don’t pass out for lack of air. Even higher and air planes can’t fly because their wings require air to provide lift.

As you ascend in an airplane and the air pressure decreases, the air trapped in your inner ear will cause your eardrums to push outward. This expansion causes not only the discomfort you feel before your ears "pop," but also a decrease in hearing ability, because the pressure on your ears drums makes the sound harder to transmit.

Your body can equalize the pressure between your inner ear and the atmosphere by allowing some air from your inner ear to escape through the Eustachian tubes, two small channels that connect the inner ears to the throat, one on each side.

When they open, you feel the pressure release and you hear the change because it’s happening in your ear. This equalization of pressure is the "pop."

On the way down from an air plane flight, the air pressure increases, while your inner ear is still at the lower pressure it has adjusted to. Now, the extra pressure pushes the eardrums inward.

Eventually, the pressure will equalize again, but many people don’t wait, they just hold their nose closed, close their mouth and blow. Because the air from their lungs has nowhere to go, it is forced into the inner ear through the Eustachian tubes, "popping" their ears.

This effect can happen to people driving through the mountainous areas or riding elevators in tall buildings, but it is more noticeable on airplanes because the altitude changes quickly and they fly higher than buildings or mountains.

Wouldn't holding your nose, closing your mouth and blowing work faster than the jaw thing?

Free Diving - Tanya Streeter

Mermaids may not be real but it certainly seems that Tanya Streeter is part fish, part human. How else can you explain Tanya's ability to dive more than 350 feet (110m) underwater with just a single breath? She truly is a freak of nature.
Tanya grew up in the Cayman Islands in the Caribbean so she's always felt comfortable around water. When she was a kid she was always known as the girl who could duck-dive for the deepest sea shells - but she never figured she would be able to dive deeper than anyone else in the world.

She only learned exactly how good a diver she was in 1997 when she attended an introductory class on free-diving with a couple of guy friends. Tanya was the only female in the class and no one wanted to dive with her at first because she was a girl. But she surprised her teachers and everyone else in the class when they saw how long Tanya was able to stay underwater. Her teachers immediately offered to coach her and within months Tanya was breaking all kinds of world records.
