He was in his early 30s and had the heart attach while on vacation with his wife and 1 year old. He was a great person and its sad to see him go. They put him in a state of induced hypothermia to try and save his brain. An MRI today revealed his brain was damaged too much and his family decided to take him off the ventilator.
My job has a ton of young people (10K employees and 90% of them are younger than 35). I should mention, though, that he works right down the hall from me so I know him. We don't see this type of thing happen very often.
