I had a friend who would catch them out of the air and eat them, said it kept them from biting him.
I don’t know. If I am outside with others (like on the porch or in the yard - not counting wilderness areas where they are aggressive) I don’t get bitten but if I am alone they do bite me.
I do run cold, can stay cool in warm weather, don’t sweat easily, and I breathe quite slowly. So my money is on warmth and CO2 as the biggest factors. Other people are probably louder and distract them away from me.
ETA This was interesting too, maybe you really are mosquito bait.
