I am not that superstitious. :-) Interesting story though.
Besides, only 2 out of many thousands of players who played Berzerk. The one guy was overweight and both likely had heart issues, some of which can be hard to detect (look at one of the top college athletes who was in top shape and died of a heart issue very unexpectedly).
I am far more likely to get killed driving to work on the highway every day...
