Uhh, maybe? Shark attacks are quite rare, but I think you might be underestimating how many bites just result in stitches. Talking about "shark attacks" here. Not "Great White shark attacks". Likewise you're certainly underestimating how many airplane "accidents" don't result in any injury (again, not talking about "commercial airline accidents").
You run into mosquitoes 30k times a year, one of them may kill you, and most of the time you could have saved yourself on your own.
