That's so sad Iceman.

When someone, especially a young person, around your age dies so unexpectedly, it sure gives you a reality dose. None of us are exempt from unforseen death. Makes you really step back and appreciate "just being alive."
When I was around 22 or so, one of my friends literally, at 22 dropped dead on the job. :p Autopsy didn't show anything and cause of death was shown as "unkown".

What a shocker though. My condolences.
