Naked Mole Rats Don't Get Cancer

In the world of animals, naked mole rats are a super-species. They don't get cancer, are resistant to pain, and can survive up to 18 minutes without oxygen. But perhaps their greatest feat, is that they don't age.

Naked mole rats seem to flout the Gompertz law, a mathematical equation that describes how the risk of dying rises exponentially with age; in humans, for instance, it doubles every 8 years after the age of 30.

Except for the Naked Mole Rat, the Gompertz law applies to all mammals after adulthood.
