Tomorrow by this time, I'll have gone into the chamber of cold death.
Just talked to the guy at Viking CryoTherapy in Los Gatos, CA. He has a facility within about 5 minutes from me. A commenter hooked me up. We talked a while about my background with things, and he agreed to hook me up with the max.
-300 degrees fahrenheit, somewhere between 2.5 and 3 minutes in the gauntlet. Liquid nitrogen fueled. I'm taking a camera and hope to report back.

Remember: No woo. No asteroids; just rational science, individual experimentation and results. Even if an asteroid did hit thousands of years ago and shaped human evolution, you're still the fuck on you're own right now...today! Get over it, get fucking used to it, and most particularly, quit listening to fucking gurus.
