Do you get bitten a lot by mosquitoes, and other biting insects? I do. Do you know people who never get bitten, even when they are in the same place as you, surrounded by hordes of potential biters? I do.
For as long as I can remember, I have been plagued by insect bites. They have ruined holidays, made day trips a misery, and kept me awake at night. In the worst case, they managed to badly infect my legs, and I wanted to return home early from Crete, but couldn’t get a flight.
I have used every repellent known to man, and every after-bite treatment sold on the market too. Even if they reduce the number of bites, they never stop them completely. Yet I was once married to someone who was never bitten at all, in the ten years we were together. She could sit next to me watching them swarming around me, but as far as they were concerned, she didn’t exist.
I found this article suggesting why only some of us are selected by those flying pests. They have been doing some research, and come to various conclusions.
It won’t stop you being bitten, but it might explain why.
