Great tan in Antarctica?

If you live in a place such as Antarctica, Alaska and the Arctic you can keep dark skin due to the fact that a large percentage of their diet contains fish as they live in a coastal area. Fish contains a lot of vitamin D so you retain your tan without that many UV rays. Normally I would say "if you can't take the heat get out of the kitchen" but in this circumstance I would say if you can't take the heat go to Alaska and you'll keep your great tan.

Why do people have different skin colour

People have different skin colour mainly due to genetics and the radiation from the suns UV rays.
Generally people who live closer to the equator have darker skin than those who live nearer the poles. Skin absorbs the UV rays from the sun and can turn a certain amount of this into vitamin D. In countries near the equator people absorb way more UV rays than is the amount for vitamin D. The UV rays then start to tan the skin. Over hundreds of years peoples skin has got darker and darker.
In countries nearer the pole we don't get enough vitamin D so therefore don't have as dark skin as those who live near the equator.

Hair Colour History




http://bit.ly/2jH4NEA
Hair styling and the importance of hair in Ireland started in the Celtic times. For example when monks had a tonsure it was widely discussed, mocked and admired by the lay people.
Supposedly brunettes connected with aliens and blonde haired people supposedly had a good relationship with god. For a formal occasion hair was curled in ancient Ireland.
