But does this string regeneration itself carry a limited life? Perhaps hard to discuss this without talking about integrals of strings... I guess a better question might be: Is it extrinsic or intrinsic factors that prevent string regeneration? Are the oldie stem cells old because they were damaged? Or because they were pre-programmed to wind their division down over the years? My stem cell knowledge is poor =(Because the string regenerates itself readily in youth, but for whatever reason ceases to do so in old age.
