Esat - done it - the exhaust t thing is not true since it takes very little pressure to inflate the lungs, and the eihter you have to agree with that or you can't tell me that there is too much pressure from a reg. Besides, a bright guy like you should be able to operate a reg after all these years. I've seen you use chopsticks, so don't give me any bull. What comes out of your lungs is not as good as anything out of a reg, anywhere any time. As you also know, these victims tend to crank up right away, and then they need to go ahead and breathe the demand reg, not some silly bag and mask. Besides, fast action is eveything, supposition and what ifs are for the losers and the dead. You know, we have tons of witnesses to our events like this, and if you ever saw us respond to an emeregency, all you would be saying is "WOW", not trying to find a chink in the armour - our track record is too good and too long for bullshit. Last time I talked to Arielle Latulippe on the phone, she was alive. Tell her it doesn't work, and that Ray shoud have jerked off like the rest of you are recomnmending. Again, thank God that we do not have to deal with the attitudes out there, and it is getting really obvious why we do not have the accidents and everyone else does, and we do all the crazy stuff and nobody else does anything but die trying to get to first base and then make up a bunch of excuses. That is called incompetent bullshit and being a weenie. It works, Esat. Done it.
