Quite. Folks with the recessive MC1R gene for red hair, like myself, are at much higher risk for skin cancer since we don't really tan, only freckle. Interestingly, this gene is also linked to a vitamin K deficiency, lower tolerance for thermal pain and has implications for anaesthesia and post-operative pain management.

Inexplicably it also correlates with a higher tolerance for electrical pain, which might be a useful adaptation for hackers :)
