why must i be so darn tasty?

I can empirically confirm the conclusion that mosquitoes have preferences in victim selection. I am a friggin’ mosquito magnet. But what the heck is this?:

It turns out that what you long thought to be true is true: Mosquitoes prefer biting some people more than others. "Some people are just more attractive," said Ulrich Bernier, a research chemist with the U.S. Department of Agriculture.

Bernier has identified some of the body chemicals that repel mosquitoes but wouldn’t say which ones. There are patents involved but the research is encouraging, he said.

What’s with this patent nonsense from somebody who works for the government?
