The more I read about blackouts, the less I was tempted to push it. Getting cautious as in my middle age.

I was initially certified in Hawaii, then had the fortune (or misfortune) of going to Guam for my next duty station. Rock in the middle of nowhere, but great diving. I was in the same berthing area as the ship's divers--great guys, if a little crazy. Sadly, one did a breath hold dive and had a "shallow water blackout" and drowned. Kid was only 19.

Sad. Even buddy up it can still end ugly. Tanked and shallow is my motto now that I have kids. No need for a test beyond that.
