According to a new study, "attractive" people have better immune systems.
How the study worked was 79 women and 80 men at Texas Christian University had their photos taken and their blood drawn.
The participants were photographed from the neck up and were ordered to keep a "neutral facial expression."
The women were also not allowed to wear makeup.
After, 492 other volunteers were asked to rate the facial attractive of each person based on the photos.
Then the researched cross-examined the ratings with the blood test results and found the more-attractive participants' blood found to have higher rates of phagocytosis-- "the process by which specific white blood cells ingest foreign particles."
