Skin protects the insides of the body.
Human skin can range from light peachy cream colour to dark brown
depending on the amount of melanin produced.
Sun exposure and genetics can also play a role.

LONGEVITY.- Died, last Saturday, at the Countess's Bush, county Kilkenny, Mary Costello, aged 102. Her mother, Matilda Pickman, died precisely at the same age. Her grandmother's age is not exactly known, but it exceeded 123 years, and long before her death she had to be rocked in a cradle like an infant. Mary Costello's brother lived beyond 100 years; at the age of ninety he worked regularly, and could cut down half an acre of heavy grass in one day.
