When you walk through the park in the summer you see some sunbathers. I don't know about you but I always observe white folks. Ordinarily, the people you should see should be black skinned people because they need the intense sunlight most. Black skin is a marvel. It is black for a reason. It evolved to be black so as to be able tap into the Sun and get those properties that will give you long life, full of health, stronger and biologically efficient. The white skin needs the Sun but not that much. More than fifteen minutes in the Sun without sunscreen and they will get burns and ultimately peels. Black folks need it far more and they don't get scorched in fifteen minutes even without sunscreen. But some Africans and other diaspora Africans avoid the Sun. Is it not ironic that while some black folks are lightening up, some white folks are darkening down? They call it tanning and it does not come cheap either. People of African descent, living in cold climate, can have a natural Sun protection factor (SPF) of up to 13 as compared to 3-4 for whites. For equatorial and other hot weather blacks, it is even better. This advantage for African Americans and black immigrants, can also be a disadvantage. It is a double edged sword for black people not living in equatorial climate. You just need to have proper information with which to turn the disadvantage into an advantage.
