Succinctly put. But aging is not a singular process. We age biologically, psychologically and sociologically and the aging experience is determined by the unique interaction between these various clocks. Says Dr Gurcharan Singh, physician and founder president of the Yoga Natural Health Education Society: "This kind of machine-driven local treatment can only be temporary. One has to treat the body and mind as a whole or, after a while, the 'claimed' anti-aging process will be reversed again." Professor Vinod Kumar of the Department of Medicine at the All India Institute of Medical Sciences, a specialist in geriatrics, agrees that active muscles are the secret to health, longevity and youth, but declines comment on the Isogei effect. "These machines are totally out of our domain," he says. "We are concerned with medicine and these machines are for beauty par-lours. They may have been tested scientifically abroad but regarding their efficacy, I have no idea."
