Guest guest Posted November 21, 2002 Report Share Posted November 21, 2002 Hi All, See the attached/below for the lighter side view of CR and its scientists. Cheers, Al. ............Another optimist is Dr. Roy L. Walford, a pathologist and researcher at U.C.L.A. who served as the team physician during the Biosphere 2 project, in which a squad of humans lived for two years inside a sealed-off indoor ecosystem. Walford's baby is calorie restriction. This sounds strange, but it's based on a long-recognized fact: reducing calorie intake in lab mice extends their lives dramatically, and it's the only technique proven to do so in a mammal. Whether it works for people is still an open question - data released in 1997 indicates that it works in lower primates - but Walford is a believer. He told me that the de facto calorie restriction practiced inside Biosphere 2 (the Biospherians weren't able to grow enough food in there, so they fasted involuntarily) resulted in a range of quantifiable benefits, like dramatically decreased cholesterol levels. Some of Walford's colleagues think he's gone off the deep end with his extrapolations, but at 73, he was still practicing the gospel, living on an 1,800-calorie-a-day diet, as opposed to the recommended 2,000 to 2,500 for adults. He insisted that a person who started calorie-restricting at 18 would have a chance of living to 160........... At the end of my visit, Kent introduced me to Dr. R. Spindler, a professor in the department of biochemistry at the University of California at Riverside. Spindler was hired to help direct the Life Span Project's rodent research on the effects of supplements. He's also an old hand at researching calorie restriction, which for decades has been known to extend the life of lab mice. (The mystery is how.) A dapper, compact man who practices a mild calorie-restriction regimen himself, Spindler offered to show me his lab at Riverside, so I followed him over. En route, I sorted my thoughts on all this stuff. Larry and Herb and Durk and Sandy seemed harmless enough, but obviously, I had to be against the dog-slaying. Calorie restriction seemed O.K., but I did have to wonder if that would be a desirable way to " live " just to tack on a few more years. A typical platoon of calorie-restricted mice eat about 40 percent less than their unrestricted counterparts. Put in terms I could understand, that comes out to about 100 percent fewer trips to New Orleans. The idea of living life as an extended pursed-lip tightrope act seemed too rational to be much fun. Put another way, it seemed too " Houyhnhnm. " Say what you will about the superior moral virtues of the horse people in Gulliver's Travels, but admit this: they were awfully boring. Little wonder that no one mourned when they died. They probably couldn't tell the difference. The s weren't proper role models, either - they were too animalistic, nasty, and ignorant - but at least they knew how to have a good time, even if their primary amusements were howling, fornicating, and defecating. Inside his lab, Spindler introduced me to his wife and lab pardner, Patti Mote, a kindly woman who loaned me a white coat. We walked upstairs to a small room where the racks of mice are kept. Against one wall was a rack of individually caged, calorie-restricted mice; against the other, the so-called " ad libs, " furry fatties who could eat whatever and whenever they wanted. With dramatic consistency, I was told, the fatties were unhealthier and died sooner. I leaned in to study them closely. They looked sluggish, lazy, and swollen, like little fur-covered sausages with hangovers. By contrast the dieters were alert, pert, and active. Even though I'm a naturally too-skinny guy myself, I felt no kinship bond with the fit-and-slim mice, who struck me as too smug and Houyhnhnm-like to love. I liked the fatties. The s. The Spindlers grabbed a Houyhnhnm mouse and a mouse and showed me " the dowel test, " a measure of mouse dexterity. They laid a long wooden dowel over a dry sink, creating a sort of Dowel Bridge over Sink Canyon. They put a dieter on the dowel and slowly turned it. It kept its balance, no problem. Then they put a through the same paces. The hapless tub clutched and blobbed and quickly fell. But ... was I imagining it? He seemed to be smiling as he tumbled. " He fell off without me even rolling the dowel, " Spindler observed dispassionately.......... Walford, the staff M.D. inside the Biosphere 2 bubble, is a longtime life-extension researcher, focusing on calorie restriction. http://www.walford.com/index.htm Quote Link to comment Share on other sites More sharing options...
