Dates of death, and corresponding ages, are not typically reported to registries.

The Longevity Project opened up the possibility to learn just how long

Peruvian Horses live. From a sample of all North American registered

Peruvian horses born in 1995 or earlier, and belonging to owners of horses

on the Longevity List, 40% are identified as having lived into their

20s and 30s—with many still alive. Horses on the Longevity list are not unusual

outliers. . . rather, they represent a much larger number of Peruvians that live

past 20. From owners of horses on the Longevity List, we learn that 39% of

Peruvian horses living past twenty live 25 to 39 years.
