If one Grizzly bear swatted you upside the head....you probably wouldn't like that either.
Not plausible. If every mosquito on earth bit you. You would likely die from suffocation long before blood loss became an issue. :)
Each mosquito takes .01L of blood?! That's 10 ml, or about 1/3 oz per mosquito.
Must be some pretty big mosquitoes where you come from.
One mosquito bite is too many for me. :)
