People with slender faces more likely to be left-handed

People with slender faces are more likely to be left-handed. Slim faces are also linked to susceptibility of tuberculosis. That's according to a new study from the University of Washington School of Dentistry.

Researchers looked at over 13,500 faces. People with slender faces were 25% more likely to be lefties.

The link may shed light on the evolution of left-handedness. The hypothesis is that the genetics that shape facial features and TB-susceptibility can up the chances of being left-handed. The geographical coincidences seem to add up.

Researchers say Britain was called the tuberculosis capital of Western Europe. The UK has a lot of lefties with slender faces. Slender faces and jaws were also linked with an overbite.

More studies are needed to prove the findings.
