LMAO do you even biology? Do you understand what indigenous means? An indigenous person from south or north america cannot be white, they did not evolve or descend from Europeans.
And that completly depends on the climate people live in. People age much better in temperate climates. You take a very pale person and a tanned person chances are they'll age similar amount in a cool temperate country like a lot of Europe. If you put them both in a sunnier climate, like around the mediterranean then the pale person will age a lot quicker.
