Divers carry knives for a reason (?)

I understood that when the breathing reflex became too great, one inhaled water and drowned- probably heart failure without O2, though I'm guessing the heart might continue for some very small time after the brain shuts down without support. Now, I'll read the article and see.

Y'all are overcomplicating a simple matter. I've known for a long time now that people can't breath underwater like fish, or fly through the air like birds. ;) :D

Here's something more challenging. Normally to create and maintain a vacuum, you require a sealed container. Outer space is a near perfect vacuum. Wrap your head around that. :p

I see what you mean. NASA should get into stabalizing handle slabs. Its so simple. You're diabolical Sarge.
 
Not really surprising at all sarge. Even seen pics of the planets from outer space. We're all ants in a giant marble jar. We just can't find the edges of the container. I'd be willing to bet at the bottom of the Yucatan crater is a giant aggie.

Sarge is A-1 correcto.

From the 'wrap your mind around that', department:
Carter and I sometimes ponder infinity, the stars going on forever, and how that could be. It's funny how one of the simplest things of all, stars overhead, becomes unimaginable, and how the sit-coms we watch, alledgably creative, are trite in comparison.


....a giant aggie?

Upon water entering the airways, the body experiences laryngospasm, that is the Larynx or the vocal cords in the throat constrict and seal the air tube. This prevents water from entering the lungs.

Water enters the stomach in the initial phase of drowning. The laryngospasm relaxes after unconsciousness and water can enter the lungs.

IIRC this might be correct
 
My answer to Sarge's vacumn question;
There's just not enough stuff to go around.

Fact: space is a vacuum.
Conclusion: the universe sucks.

I'm a glass-is-half-empty sort of guy. ;)

How's the universe work? At a certain point it becomes a philosophical question. Is there an end to it? Where is it from? Where is it going? We'll probably never know. Take your best guess.

As for me, I think it's the back of a giant turtle. Before any smart guys ask what the turtle's standing on, it's turtles all the way down. Hah!
 
I read the Wikipedia explanation on drowning. It was very informative.

I failed to see any reference to instant death due to salt water entering the lungs. :confused:

According to the Wikipedia explanation drowning with take time, and never been instantaneous, but perhaps I missed something.

Thanks.
