Will Gene Therapy Change The Human Race? (show 205), first airs October 2000.
You’ve heard of ‘Designer Clothes?" How about "Designer Kids?" Take your choice — girl, boy; smart, tall; beautiful, graceful; musical, mystical; ambitious, ambidextrous? Gene therapy is the treatment of disease by altering human DNA, which are the special molecules in all our cells that carry all genetic information. Gene therapy may sound like a normal medical advance. It is not. The restructuring of our genetic material, with the power to heal and cure, is a revolution. But what’s the difference between genetic therapy and genetic enhancement, between curing old diseases and creating new bodies?…. But if we intervene, and adjust human genes, do we impact, and alter human evolution? 
Participants: Anderson, Ayala, Nuland, Stock, Tobin

Can You Really Extend Your Life? (show 108), first airs June 2000.
How long will you live? Think you’ll make it to 90? 100? 120? With all the nonsense about longevity, it’s time to learn the facts, fads and fallacies of living longer. Long life is humanity's ancient and perennial goal. Prophets promised it; explorers searched for it. We all want our loved ones alive and well, vigorous and vibrant. We toast, "To Life". The trick is to live younger, not just longer. I’d rather disembark at 90, having lived like a 40 year old, than slog on to l00, having trudged along like a 90 year old. What’s the Biology of Aging — and the best, most sensible advice to slow it? How do you find true longevity amidst the clutter of conflicting claims? 
Participants: Anderson, De Vany, Nuland, Stock, Walford

Does Sex Have a Future? (show 114), first airs August 2000.
Cloning for reproduction? Virtual sex for recreation? Erotic adventures on the Internet? But all software and no hardware? All pleasure and no intimacy? Is something missing here? Sex already pervades modern life, transforming values and changing morals. Now what happens when technology multiplies sexual options and accelerates sexual shifts? What’s the impact on personal relationships and social cohesion? To assess the future of sex, we must understand the nature of sex.
Participants: Abramson, Bullough, Stock, Penner, Penner

Who Needs Sex Therapy? (show 209), first airs November 2000.
How’s your sex life? Like to make it better? Do you even know what "better sex" even means? Talking about sex in public used to be off limits. Today there’s more talk and obsession, but perhaps less pleasure and fulfillment. Sex therapy, traditionally, was limited to few people with odd problems. Sex therapy, today, helps many people with normal problems…. What’s a "normal" problem about sex?
Participants: Abramson, Bullough, Nuland, Penner, Penner
