NJMike:Rock on, rockjock3! Thanks for this one...so will the real truth please stand up?
Isn't it true that human blood in water will attract sharks from miles away????
Potential future bleeders in the water need to know!
DivingCRNA:Myth: Back inflate BCs (and BP/Ws) "push your face in the water".
It is possible to end up with your face in the water on the surface, if you have all your weight on a belt on your front and/or you overinflate your BC on the surface and/or you do not simply lean back and relax on the surface.
In any of the possible scenarios above, nothing "pushes your face in the water". The BC bladder floats, and your weight, or the weight of your weights PULL your face in the water by GRAVITY.
There-I never want to hear that myth again
Pathfinder:Any blood, not just human blood. Sharks detect it at 1 part per million and smell it from a distance of approximately 1/4 mile. Not quite "miles" away.

CAPT HOOK:Agree with Walter!!
All these "expert" sources quoting Wikipedia!
MikeFerrara:Being overweighted (needing air in a bc to be neutral) is just a fact of life when diving all but the warmest waters with the smallest tanks.
Huh?Temple of Doom:I used Wikipedia to illustrate that surface area was dependant on drag
Temple of Doom:Quoting Wikipedia is perfectly fine if you take it with a grain of salt.
Rick Murchison:Huh?
Methinks there's a cart/horse inversion goin' on here...
