Fati valet hora benigni - Juvenal

You should pray for a healthy mind in a healthy body.
Ask for a stout heart that has no fear of death,
and deems length of days the least of Nature's gifts
that can endure any kind of toil,
that knows neither wrath nor desire and thinks
the woes and hard labors of Hercules better than
the loves and banquets and downy cushions of Sardanapalus.
What I commend to you, you can give to yourself;
For assuredly, the only road to a life of peace is virtue.

Anima sana in corpore sano

No man becomes bad all at once.
