“The best age for a guerrilla fighter varies between 25 and 35 years, a stage in which the life of most persons has assumed definite shape. Whoever sets out at that age, abandoning his home, his children, and his entire world must have thought well of his responsibility and reached a firm decision not to retreat a step.”

“Every stage of life has its troubles, and no man is content with his own age.”
Omne aevum curae; cunctis sua displicet aetas.

The Almost Perfect State (1921)
Context: Of middle age the best that can be said is that a middle aged person has likely learned how to have a little fun in spite of his troubles.
It is to old age that we look for reimbursement, the most of us. And most of us look in vain. For the most of us have been wrenched and racked, in one way or another, until old age is the most trying time of all.
In the Almost Perfect State every person shall have at least ten years before he dies of easy, carefree, happy living... things will be so arranged economically that this will be possible for each individual.
