I think that you all are taking the song too literal. People die for many reasons at any age. A 28 year old dying from a heart attack is just the same as a 12 year old dying of cancer. It's tragic, yes, but because this young man happened to actually make something of himself his death is questioned. If you read in the paper that a 28 year old died of a heart attack you wouldn't question a damned thing, but because this man had the access and means to commit suicide, all of the sudden there's a question involved. Grow up.
As for the song itself, love it. It doesn't need to have the same meaning to everyone in the general public. Listen to the song, decide why you like it, decide what you take from it and leave it at that.
