Sorry, we don't make the rules
If you find that you're rarely sick, it could actually because you're really sexy.
It turns out, attractive people have better immune systems, according to a new study of blood tests.
Scientists at the Texas Christian University asked people to rank over 150 people based on their looks.
Participants with classic indications of beauty - such as bright eyes or symmetrical faces - had more white blood cells, which work to fight off infection.
It also found typically good-looking people were less likely to have experienced development problems in the womb or during childhood.
Leader of the study Summer Mengelkoch said
"People who go out to a bar looking to talk to someone attractive are often dismissed as being shallow"
"But they are really just following their instincts to find a high-quality mate.'
So the next time you find yourself picking up a sniffle, it might be just because you're not hot enough!
