At 34 years old, BJ Penn may still have some good fighting years left despite retiring after his recent fight. Penn hasn't made a confirm committment either way, and spoke to Fuel TV about a potential return:

"I'm still just hanging out, honestly. At this moment, my guess is probably a little better than yours, but I don't know. I'm enjoying what I'm doing. I am training. I'm starting to train a bit more, for my health a lot. I'm a fighter, I'm a fighter deep inside. If I felt it, if it ever comes back -- not saying that it's gone -- I don't know.

You know how being a fighter is, your mind changes from time-to-time. Of course I'm looking, Anderson (Silva) he's 39 and he's in there fighting, I'm like 'I'm 34, why can't I fight again?' It's gotta be right. There's no sense in me going back into the Octagon and getting beat up in front of everybody, that just doesn't make any sense."
