Last month, the world's oldest person died. Spanish woman Maria Branyas Morera was one hundred and seventeen years old. She lived through two pandemics, two world wars, and the Spanish Civil War.
She was what's known as a supercentenarian -- someone over the age of one hundred and ten. And the number of supercentenarians globally is growing.
