Stephen Furst Dies

[Jackalope]

Jerry Doyle died of alcoholism.

Stephen Furst died from complications related to his weight (which he was trying to lose).

Carrie Fisher died from long term drug abuse.

Not much room for generalization.

I think the only generalization I might care to make here is that the entertainment industry seems to have more than their fair share of untimely deaths. I wouldn't hazard to guess whether that was cause, effect, or unrelated though.
