Two things scientists have known: calorie restriction and exercise seem to slow aging. One thing they didn't know: why. Now, researchers at Harvard have found evidence that the slowing of aging may begin in nerve synapses. An abstract of their work can be found in PNAS, and far more easily understood report on their work is available in the Rodent of the Week column of the LA Times. The Times reports that researchers examined mice that were genetically
engineered so their nerve cells glowed in fluorescent colors. Some mice
were placed on a restricted-calorie diet while others were put on a
one-month exercise regimen. As people age, the neuromuscular
synapses don't fit together as tightly, resulting in less efficient
nerve transmission and causing muscles to become weaker. In the study,
however, the mice on calorie-restricted diets showed reversal of the
deterioration in their neuromuscular junctions. The mice on a one-month
exercise regimen were already elderly at the start of the study but
still showed some reversal of damage in the synapses.

Hay William!!! Check out my reply,on the back pain page.I hope you like it. I wonder if fasting will have the same affect on aging as calorie restriction does? EVERYBODY HAVE A BLESSED DAY!!!! DOCTOR Bill C. Southeast (coner) of Texas.
