T-Rex won't just drop dead once they hit 32 years old right? .....right?
Aging, Diseases and Death
The majority of the deaths were caused by diseases or health problems.
E.gs., died earlier due to untreated wounds or later (old) due to weakened Immune system and Bodily Functions making them more exposed and fragile to disease.
Basically how it is logically and irl.
Suggestion:
Longetivity of Captivated vs Wild Animals
E.g., T-Rexes lifespan were usually 32 years old (Wild), but captivated T-Rexes should have a big chances to live way longer, even up to a decade more. Since their well-being got taken amazingly compared to the gamble life of wild T-Rex.
However, how longer they will live should depend on us. The better and earlier we take care of them, the longer they will generally live compared to their wild lifespan.
A few key reasons (I will use slightly more complex terms):
With great care, they will have minor-no stress.
Stress is a huge factor to biological aging, and lesser stress earlier will extend their live more.
The earlier, the better and longer
The more they age (biologically) due to some things including majorly stress, the higher the risk of diseases or health problems. Making their lifespan shorter.
So by being a great builder earlier, our animals could have very high chances to live a beautiful longer than expected life.
Inversely will also happen, the worse the care we give to our captivated animals, the shorter their lifespan and they could even died earlier than the wild counterparts
The risk of unexpected deadly disease still could occur, but just like the stress-factor, the chances will be lowered depending on how good and early we take care of them.
Also, devs can introduce routine health checkups, earlier diseases symptoms and treatment mechanisms.
