I gave this more thought last night. (I just can't help it.) As BrainSurgeon, said this is not a legitimate cause for concern.
From our abdomen on down we are basically sacks of water which is virtually incompressible. This is a basic Hydraulics 101 problem. There is a natural pressure balance taking place. My bladder sphincter could hold back 6" H2O positive pressure this morning. (Don't ask). The 6" pressure differential will be true even if I am under many feet of water. I figure the bladder is a bit like a water balloon. As long as there is no air inside, it is incompressible. Water can't make it up the (sadly) short length of tubing. I'm safe. (Except for diffusion and Brownian movement.)
Geezer, You're right. Jacques Cousteau dove even in his 80's. I doubt his "equipment" could hold back 50 ft of water pressure. It didn't have to. Pressure balance took care of it.
Steve, I suppose I could shove a small poppit valve in there if I was really worried.
PA69 (Bob) Thanks! Your answer was just what I needed. Please thank your diving instructor for me. That descript
ion makes perfect sense.
Years ago at the office we used to describe a certain mechanical tubing connection as being "Tighter 'n a frog's anus", meaning it cold not leak. Well, based on this discussion I figure Froggy's butt didn't need to be so tight at all. Pressure balance did the work. Hmm... how am I going to measure that?...
I've got a "heads-up" for all the fish in Lake Ontario. Better start getting used to higher urea concentrations. I'm goin' in!
I'll make reservations for you guys in Lake Ontario if you plan on attending the GFMPH Retreat.
Age 56. Perfectly healthy with no problems until getting the results of my first routine PSA test on April 8th: 17.8. My GP does not believe in general PSA screening so I did not get results during my 50 year physical.
May PSA: 22.6, 3 weeks later: 23.2.
