Playboy tycoon Hugh Hefner is planning to have a face lift - and insists it's perfectly acceptable for men to undergo cosmetic surgery. The 81-year-old magazine boss admits he has already gone under the surgeon's knife for a neck tuck and a new set of teeth, and refuses to rule out further surgery in his pursuit of youth. He says, "I'm thinking of having a little face-lift. There is nothing wrong with plastic surgery. I think it is absolutely fine for men - I have already had teeth implants, and a few years ago I had a neck tuck. "We are dealing with a whole different set of things physically now because we live so much longer."
