Every time I think I would really enjoy spending some quality time in Japan, I see something like this, and then I just don't know.
What can I really say about this? What can anyone say, other than "Don't do this, it is a really bad idea." My mother spent a good fifteen years keeping my head out of normal plastic bags, and here's a guy not only putting one on his head, he gets encased in it and has a friend vacuum the air out.
I give up trying to understand anything, ever.
The vid might not be safe for work. Who knows anymore?
