Inside chromosomes are telomeres that age as we age, and may serve as indicators of how long we'll live. Wrinkles may betray our age externally, but our cells divulge their age -- and chronicle life's toll -- at the tips of our chromosomes. These tips, called telomeres, may also foretell our risk of early death.
