Heck I'm surpised he was even able to get in the tub at that level!!!
.32 is pretty average for a hard core alcoholic. They could be quite functional at that level, in a bizarre sort of way of course.
.6 might kill the person with an untrained liver but I have seen a veteran walking and talking at .5 blood level before.
Those guys would start going into withdrawal if their blood level got down as low as .32!
