Slave longevity

For a slave girl to end up in Jabba’s clutches, it’s practically a death sentence. Her entire body is used for the Hutt and his court’s pleasure day in and day out, until one day she either slips up or Jabba gets bored; when that happens, it’s down to the rancor she goes. It’s not a question of if, but when, so how long do you guys think the average slave lasted before Jabba disposed of them?
