Life span of a leopard gecko?

I don't have much personal experience with this yet with leos. From what I understand, Thor is pretty much on the money. 5-8 years Is pretty common if cared for well. The problem with females is people over breeding. Especially if they try to do it twice a year, that's add many as 12 clutches of eggs. The poor little things bodies never get a chance to recover. People who are blue concerned with selling babies than caring for the animals. And even more so its they're not being fed properly throughout the breeding season.
