I have said on other threads, I am alive today because of the accident forum. The speculation about possible causes and solutions to both avoid the cause and to solve the speculative cause in another thread absolutely saved my life. My buddies left me, I was alone about to panic and in serious trouble. And I as I thought, ok this is about to be it. I went on a dive I had no business going on, I remembered a thread just a few days before and I recited what I could remember over and over again on that long trip to the surface doing a free assent with no line or visual reference. It was several minutes and looked bug eyed at my computer and kept saying the solution over and over to myself. Up to the point I got in trouble, my foolish profile was following in the footsteps of someone who didn't make it. I didn't want to finish that profile, but I was close to doing it.
I am always sorry to hear when someone loses a loved one no matter the cause in or out of the water.
And I have told my family that if I die while diving, that it is to be fully discussed and speculated about until people get tired of doing it. I will already be dead and no mean thing or kind thing done here can bring me back, but it just might allow someone else to make it back to their loved ones. I have made mistakes before and I will make them again. At some point either a mistake of mine or a mistake of someone else will get me if disease doesn't first.
