London, Nov 10 Jane Fonda has said that it's her sex life that keeps her "better than ever" at 71 years of age.onda, whose 1982 workout video is still the biggest seller in the market, said an active love life was partly responsible for keeping her looking young.

"How do I still look good? I owe 30 per cent to genes, 30 per cent to good sex, 30 per cent because of sports and healthy lifestyle with proper nutrition and for the remaining 10 per cent I have to thank my plastic surgeon," the Telegraph quoted her as telling German newspaper Bilt.

"I'm 71 and physically don't feel so good since I'm in pain. But I'm happier, the sex is better and I understand life better. I don't want to be young again," she added.

The 'Barbarella' star is apparently planning a fourth marriage to music executive Richard Perry, 67.

She has previously been involved with Donald Sutherland, her co-star in the 1971 movie 'Klute', and French journalist, author, actor and director Roger Vadim. (ANI)
