The Aging Problem
There's nothing like a new car, and you never forget the day
your drive your first one off the lot. But eventually your new car
ages, the catalytic converter becomes less effective, the exhaust
isn't very clean, things begin to rust and the engine suffers wear
and tear.
Our cells are like car engines. They have the same combustion
process, produce some of the same byproducts and clean up with
similar catalytic converters. When we're young, our enzymes (our
cells' catalytic converters) function well and do a good job
cleaning the toxic byproducts our bodies generate. But
unfortunately, like cars, our bodies don't always function like
new. As we age, our bodies produce more free radicals and less of
the special enzymes that fight free radicals causing oxidative
stress. The damage by oxidative stress leads to the symptoms of
aging.
