Pressing your luck too far

"Crocodile Hunter" Steve Irwin was tragically, but not surprisingly, killed early Monday by a stingray during a diving expedition. While it is sad that this happened, I find it most regrettable, in the sense that this was so preventable. There's a fine line between fascination and respect of nature!
Irwin was at Batt Reef, off the remote coast of northeastern Queensland (Australia) state, shooting a segment for a series called "Ocean's Deadliest" when he swam too close to one of the animals, which have a poisonous bard on their tails, his friend and colleague John Stainton said.
"He came on top of the stingray and the stingray's barb went up and into his chest and put a hole into his heart," said Stainton, who was on board Irwin's boat at the time. Stingrays have a serrated, toxin-loaded barb, or spine, on the top of their tail. The barb, which can be up to 10 inches long, flexes if a ray is frightened. Stings usually occur to people when they step on or swim too close to a ray and can be excruciatingly painful but are rarely fatal, said University of Queensland marine neuroscientist Shaun Collin.
Collin said he suspected Irwin died because the barb pierced under his ribcage and directly into his heart.
"It was extraordinarily bad luck..." Collin said.
Bad luck, or a bad choice of activity?

...Reminds me of a comic book I saw years ago entitled, "Unpleasant Ways To Die."
