I always have this fear of being disabled or something and i can no longer go with the complicated methods that require me to travel to buy supplies such as with the exit bag with inert gas method.
I need something quick and painless that i can very quickly set up without needing a lot of equipment. I like the idea of cartoid artery compression because you can do it anywhere quickly and painlessly (or so ive heard) and with minimal equipment, stuff i can usually find in my bedroom.
