Once more, life expectancy has not much to do with lifespan, and has to do
with the probability of your being killed at any time by predators,
infections, hunger, accidents, lack of parental or elderly care, etc.
Conversely, no matter how well you treat your cat, it is not going to live
fifty years any way.

In fact, lifespan has been *shortened* until sometimes in XIX century in
comparison with prehistory, and in spite of that cctuagenarians have always
existed.
