Do you ever wonder why mosquitoes always find you and bite you, whereas some people around you never get so often bit by them.
Human blood is grouped into four basic blood types—A, B, AB and O. Studies show, that mosquitoes prefer few specific blood types. A 1972 study was the first to show mosquitoes have a blood-type preference for type O blood over type A or B blood.
A followup study concluded that mosquitoes prefer type O secretors above all. Scientists have isolated proteins on mosquitoes’ antennae that detect chemical markers emitted from peoples’ skin.
This is proven, so incase you are blood type ‘O’ you would have observed that you must be feasted on by mosquitoes often. And that’s why Blood type ‘O’ people need more bug spray or gels.
