Normally we don't support making assumptions about someone because of what they look like or the color of their hair, but a new study that was published this week is claiming that people with red hair (redheads) have a higher pain tolerance compared to anyone else with a different hair color.
The study found that the cells that determine skin color also play a role in deciding how we experience pain. Since people with fairer skin are more prone to get a sunburn it also means they develop the pain tolerance.
Now this isn't to say that your friend with red hair is going to outlast you in any endurance challenge, but if they do then you can blame it on their hair!
