Do not be overfond of an injurious life

 The George Long translation of 1862:

For to continue to be such as thou hast hitherto been, and to be tom in pieces and defiled in such a life, is the character of a very stupid man and one overfond of his life, and like those half-devoured fighters with wild beasts, who though covered with wounds and gore, still intreat to be kept to the following day, though they will be exposed in the same state to the same claws and bites. Marcus Aurelius.  Meditations. Book 10.

Chrystal's 2017 rendering based on the Foulis translation of 1742:

For to continue as you have been till now, in the same life of distraction and defilement, would mark you as a man devoid of sense, who clings to life like the half-eaten beast-fighters, who, though covered with wounds and gore, do yet appeal to be reserved until tomorrow, to be cast again in their wretchedness to the claws and fangs that lacerated them before. Marcus Aurelius.  Meditations. Book 10.
