2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.


Obvious right or left wing sources will be removed at the mods discretion.

Water temp of 47 can be lethal very quickly.

Water cools the body about 25 times faster than air of the same temp. A diver in 70-degree water may go blue in the lips even with a wetsuit. 47 degrees will have your body going numb super quickly. Then you lose dexterity and start having muscle cramps all over. You lose the ability to swim away or even tread water.

It's bad.
