That's why the stroke BCs have all the pockets in them. You gotta have a
spot for the chicken bones, rabbit's foot, and tarot cards that are required
to dive that stuff.

Pure voodoo. Chicken bones and all.

What about hyperoxic trimix? Lets say 25/35 for giggles.

And, from whom should all these shingles be acquired?
