When I was an undergraduate, the University organized an October field trip to Vermont for a long weekend. On the second day of the trip, a bunch of us were having lunch on wooden tables and benches. I was seated next to and chatting with Mike, whom I met for the first time the previous day. When I asked him a question and he didn’t answer, I turned, and saw a stiff body staring ahead. I caught him as he keeled over towards me.
