Pandas are generally considered old after reaching 20 but can live for many more years in captivity, where they can be treated for diseases and shielded from accidents.

An estimated 1,864 live in the wild, where they are threatened chiefly with habitat loss, and around 420 others live in captivity in zoos and reserves, the majority within China.
