At 42 years old, Walnut was considered geriatric for her species. She far surpassed the median life expectancy for white-naped cranes in human care, which is 15 years.
(Avg life expectancy of humans without tech is prob 20, but humans could live to 100+ thousands of years ago, nothing changed, we just systemically eliminated the factors in our environments that cause non-old age death (with cancer, neurological, and cardiovascular problems remaining the last lines), eg food quality, vaccines & healthcare overall, killing & sterilising every other ecosystem around us, you know, the usual)
She lived almost 3 times the average life expectancy for her species!?! That’s genuinely insane! Imagine a human living to 180 years old!
