Steve Irwin killed by stingray

I don't understand the shock and disbelief concerning his death. I'm stunned that he lived this long. He was constantly putting himself in harms way and flirting with death. I reminds me of the shock over Jerry Garcia's death. People were surprised he died so young. I was surprised he lived as long as he did. Garcia was overweight, diabetic, smoked and had a lifelong heroin addiction.
