Why are spiders more scary than sharks?

[Keri]

If you were bitten by a great white, the effected area will take only 3 hours to digest and 5 hours before becoming shark poo. If it had bitten you next to the spine, life long permanent damage would only last 2 seconds.

You know, I don't think anyone here is arguing that a shark isn't more dangerous than a spider, but that spiders are more frightening.

Atomic weapons are more dangerous than a .45 pistol. Which am I more likely to harmed by? Like the .45 pistol, I'm more likely to be harmed by a spider than a shark.

I've got to add that shark attacks are quite rare. Fatal ones, even more so.

"Several theories have been put forward by experts as to why white sharks sometimes bite people. In this article we examine three of the most prominent theories and look at why most of these incidents are non-fatal."

Great sources.
Two out of those 78 fatalities of the white shark happened in the waters off my hometown during the last 10 years. I'm no maths person but I'd say my chances of being bit are higher than the average person anywhere else given that when I'm living in that town I'm in the same waters 90+ days out of the year. I'm not sure of the total history of great white attacks for that area in recorded history, just going on the two fatalities* I know happened recently.

*That doesn't count all the kayaks and surfboards that get "test" bit all of the time.

I should find someone to do the percentages for me.
