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 15 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.
There's a full version of the original video, which shows the player nearly suffocating. It might not be safe for work? Who knows anymore?
