So me and my friend wanted to see if the Cannibal disease was contagious, so I got to laughing and after traveling with him for a bit, he started to laugh. Now, he had eaten many guts, so that might of been the reason. I had begun to travel with my other friends (a party of about 6 people) and after traveling from kamyshovo to tisy, I had about the whole group laughing like me, and they got pretty mad about it. I want to know if it is contagious, or if it was just some coincidence.
