Are you someone who feels like a blood donor every time you step out into nature? Turns out you may be sweeter than you think, at least in a mosquito’s mind. A recent study indicates the blood-sucking nuisance may just be attracted to your DNA. Researchers studied pairs of both identical and fraternal twins and found that identical twins had an extremely similar level of attractiveness to mosquitos than did the fraternal ones. Identical twins share the same DNA, which proves that the bugs are drawn to some the undetectable odor profiles of some humans more than others.
