Benefits of Retiring?

Hey I would like to know the difference in benefits between retiring and selling gladiators! Thanks for any replies.

Retiring a gladiator gives you access to a pool of steroid-abusers (the so-called premium slaves) who can cost more than 1150 gold and are generally a much better chassis for successful gladiators than what you would normally find on the market. Rule of thumb says - sell only the totally hopeless, retire all who have a chance to meet the requirements.

Thanks for the information.
