NEW YORK: Veteran actress Jane Fonda is embracing old age - because sex is better now she's hit her seventies. The Barbarella star has undergone a series of painful surgeries recently and now boasts an artificial knee and a titanium hip. Fonda, who is married to record executive Richard Perry, 67, feels as though she is rebuilding her body from the inside out and it's giving her a new lease of life. She says, "I owe 30 per cent (of my good looks) to genes, 30 per cent to good sex, 30 per cent because of sports and healthy lifestyle and for the remaining 10 per cent, I have to thank my plastic surgeon. I'm 71, but I'm happier, the sex is better and I understand life better. I don't want to be young again." But Fonda still has a major goal left to achieve - she is planning a mountain climb once she is fully fit again. She adds, "I just had surgery on my back, I also have a new knee and a hip made of titanium. I'm slowly falling apart and feel like a walking spare parts depot. I had to have it all repaired because I want to climb the Himalayas. And at 8,000 feet, my body has to run smoothly."
