Oh, I don't know... an errant cast that firmly sinks the hook in your right eye (with worm still attached which, in and of itself, is a disgusting consideration) causing you to flail about wildly while you scream until you begin to get lightheaded and raspy-voiced and then stumble to the edge of the boat where you trip on the Coleman cooler full of just-caught fish and fall overboard into the lake where you begin to drown until that passing gator that you never even noticed in the first place grabs hold of your brand new Justin boots (with foot still nice and comfy inside) and pulls you and your fishing rod under... I'd call that a threat of death.

Of course, I could be exaggerating just a bit on the dangers of fishing.
