When I was a kid I couldn't care less about mosquitoes and during the summer most of the kids' legs and arms had mosquito bites and deep scratches, but for some reason some kids were never bitten regardless of where they'd hang out or sleep.

Not sure whether it's a good thing or not but now I am extremely cautious not to get any bites. This summer for example I avoided the backyard almost completely for this reason, with some exceptions when I covered myself in mosquito repellant spray. The mosquito candles I tried last time weren't very efficient in my case.
