There is some kind of relationship between metabolism and life expectancy if i remember it right. Generally speaking the bigger the animal the longer they will tend to live.
Think I actually read somewhere that most animals live through about the same amount of heart beats in a lifetime. So if an elephant has a fourth of the avg heartrate as some small animal then it will also roughly live about four times as long.
What makes you think these land predators are living such healthy lives tho? It probably resembles somewhat how humans lived 10k+ years ago, and i think life expectancy was way way lower then than now.
All the knowledge we humans have about treating diseases and preserving food etc adds a ton to our overall "healthiness". Drugs, fatty foods and alcohol or more like minor bumps in the road for the vast vast majority of us.
