Boys and girls - this whole thread is dedicated to explaining one bit of data, and it’s being interpreted beyond reason. The OP jumped to several conclusions (because of his increased agility?) including the main one- that his partner got bitten more than he did because of weight. This he is comparing to the number of bites he, himself, got when he was younger, admittedly heavier, and presumably somewhere else, or to the number of bites his friend got that evening. If ever there were a place to suggest attention to variables, this would be it. It seems, by the way, the research on what causes mosquitoes to bite some times more than others is not yet on the cutting edge, or we’d have some mighty effective repellants by now.
