StephenOABC saidI've watched the first and second video so far.
The first video was from the television show The Doctors.
The second video involves Nike and Runners World.
I could care less about videos. I wanna see rock solid proof from tested research.
In my own experience, I got rid of a pesky wart by freezing it off. Upon reading the instructions, I administered the "cryotherapy" (freezing) compound to my wart for 10 seconds. After that I simply waited a few days till the wart finally died and fell off. That tells me that cryotherapy = death.
If you want your entire body to die in blaze of ice, go ahead and buy into the cryo-bullshit hyperbole with fancy words and awesome videos that appeal to the uninformed.
If you want to die knowing that your life was more fun and enjoyable than any afterlife could bring you, then work on that instead of spending your entire YOLO life trying to figure out how to make your next/nonexistent life better.
