Noone is faster than a ginger running outdoors. A ginger must minimise time in the sunlight, and so run very fast very quickly to even get any benefits from running that counterct the sun exposure. Hence, by my estimation, they 'should' actually be the fastest people on the planet. How is this not obvious?

I actually don't understand why the fastest 100m runner on earth is not always a Ginga.

Something in the science is not sciencing
