If it is true that...

Changes of aging are also the result of complex interactions between organisms and their environment rather than some genetic program 1 0 2

and

Removal of an animal's pituitary or its equivalent optic gland in the case of an octopus, radically extends the animal's lifespan 1 0 2

and

The catabolic, death-inducing hormone is produced by the ovary, under the influence of the optic gland's gonadotropins 1 0 2

Then it must be true that...

Progesterone is both an anticatabolic hormone and an antiestrogenic hormone, protecting the functional systems from atrophy 1 0 2
