Hypo - (means "low"). Cavers get along just fine at 53 F, for considerable
time. 35 F is another matter. There is some formula for average lifespan
in water at different temps...I'll see if I can find it.

If you could survive much longer than an hour in 53F water without
special insulation, I'd be surprised..

There's a huge difference between being a "caver", and being immersed in
water. Clothes do no good insulating you from the cold when you're immersed
in water. And I don't know of many nudist spelunkers.

The survival time in 35 F water is probably closer to 10 minutes -
significantly shorter than a possible 1 hour in 53 F. Individual
survival time will vary greatly - fat people in general should do better
than thin people, nutrition and general health will make a difference,
etc. Wind, water currents, and sun may make a difference as well.

Even a nude spelunker would be surrounded by air, not water. Water soaks up
body heat much more efficiently than air, I think.
http://www.tntwebcraft.com/ccso/hypothermia.htm says survival time in 50
degree water depends strongly on what you do. "Drown-proofing" where you
float face-down and pop up to breath every now and then is one of the worst
options because with your head in the water you lose a lot of heat fast.
Survival time for an average person, wearing light clothes is 1.5 hours if
Drown-proofing, and 2.0 hours if treading water. With a life vest, you can
just hold still, and increase your survival time to 2.7 hours. Any kind of
activity that uses energy, including swimming, shortens your survival time.
If you can assume a fetal position while being supported by a life vest, or
huddle with other people, survival time goes up to about 4 hours. Larger
people last longer than smaller people, fat people slower than thin people.

Survival time at 53 F (average) is 1.5 to 4.2 hours. with the range
representing "low probability of death" to "high probability of death".
See
http://www.dnr.state.mn.us/information_and_education/
water_safety/bgcldwat.html
At 35 F it gets reduced to 0.5 to 1.5 hours.
Cavers immerse themselves in water for long periods. Passages are water
filled. One must be aware of the dangers of hypothermia. I only once get
into semi-serious hypothermia after a 1/2hour crawl in 45 F water and then
*sitting around*. With activity one warms up pretty fast.
You heat the water on your clothes. It is more comfortable to be
in wet clothes than to be naked. I've tried both. (Jan is uninformed
about caving.)

You only heat the water on your clothes if you're not still immersed in water.
Duh.

That is correct. I would not recommend immersion in 53 F water (about the
water temperature in Indiana caves) for more than 2-3 hours, or if signs
of hypothermia appear.

Actualy clothes can extend your survival time even if immersed in water,
depending on the clothes. Cotton won't do much, but some snythetics hold
a lot of heat even when wet. People into sea kayaking worry about this kind
of thing.
In any case, the water the worker fell into was probably not so cold as to
be a major issue. If he was alive, an hour or two would have been plenty of
time for rescue workers to find him. If he was injured or stunned by the fall
or pinned underwater, then the water temperature was the least of his
problems.

If you're not busy Friday night, day after Thanksgiving, come
on out to Green Wood Coffee House for Katie Geddes and The Usual
Suspects. 8 pm, $10. Food and drink available.

I have typed up and entered an html version of the appellate court ruling in
Cyberspace v. Engler. I did my best to reproduce the look and form of the
original documents I was faxed.
See http://www.cyberspace.org/lawsuit/ruling.html
The ruling is linked from the main lawsuit page.
Read it. It is short, but very interesting in what it says *between* the
lines.

Help! I am looking for an apartment/flat in Ann Arbor. I'm looking for
a 1-2 bedroom, with laundry and parking. I would far prefer it to be in
an old (or new) house than in an apartment community/complex.
If you know of anyone with something like this available, please let me
know.
I am generally a quiet sort, responsible and with a steady income.
Thanks!
(Did I mention I'm kind of in a hurry? Oh. I am.)

I generally liked living at Park Place Apartments on the corner of Pauline
and Stadium, if you're looking for something relatively inexpensive.
If you've got money to spend, check out Arbor Landings on Dexter-Ann Arbor
Road right before crossing over M14.. those were nice too.

Depending on the money, there are several. When I was looking, I did a few
things:
http://www.aplacetorent.com
http://www.apartments.com
http://www.apartmentguide.com
Also, the easiest way, is if you go to Apartment Search. They ended up
finding me my place. They're all over, there are several places in Detriot
area, one in Canton, and one in Ann Arbor. They can tell you the name and
phone number at (I think this is right) http://www.apartmentsearch.com
You have to go in, but it's worth it. And they do all the running around,
call the place, find out if they have one NOW or not.
