Redheads require more anesthesia

Bask in the weirdness of this one:

Little known fact: Anesthetic requirement is increased in redheads. – “Red hair seems to be a distinct phenotype linked to anesthetic requirement in humans that can also be traced to a specific genotype.”

Weird just weird. Did I mention weird? Let’s talk about it. Comment if you think this is weird. If you don’t comment, I’ll assume you’re a redhead, and can’t respond because you’re testing your anesthetic-dose-requirement… Naughty, naughty.
