Easy: Ray Kurzweil doesn’t inject hormones into his vagina.
From Newsweek‘s Oprah takedown:
In addition, she [Somers] wears “nanotechnology patches” to help her sleep, lose weight and promote “overall detoxification.” If she drinks wine, she goes to her doctor to rejuvenate her liver with an intravenous drip of vitamin C. If she’s exposed to cigarette smoke, she has her blood chemically cleaned with chelation therapy. In the time that’s left over, she eats right and exercises, and relieves stress by standing on her head. Somers makes astounding claims about the ability of hormones to treat almost anything that ails the female body. She believes they block disease and will double her life span. “I know I look like some kind of freak and fanatic,” she said. “But I want to be there until I’m 110, and I’m going to do what I have to do to get there.”
Compare with Wired‘s profile of Ray Kurzweil:
Though both Grossman and Kurzweil respect science, their approach is necessarily improvisational. If a therapy has some scientific promise and little risk, they’ll try it. Kurzweil gets phosphatidylcholine intravenously, on the theory that this will rejuvenate all his body’s tissues. He takes DHEA and testosterone. Both men use special filters to produce alkaline water, which they drink between meals in the hope that negatively charged ions in the water will scavenge free radicals and produce a variety of health benefits. [...] Kurzweil and Grossman justify it not so much with scientific citations — though they have a few — but with a tinkerer’s shrug. “Life is not a randomized, double-blind, placebo-controlled study,” Grossman explains. “We don’t have that luxury. We are operating with incomplete information. The best we can do is experiment with ourselves.”
I respect Seth Roberts. Kurzweil and Somers? Oy. Have some grace.
