Sentence examples for life span raises from inspiring English sources

The heavier birth weight of babies born to some diabetic pregnancies is reflective of this process, where the stressed pancreas accelerates growth via the anabolic actions of insulin (18); this process is also hypothesized to diminish the capacity of the pancreatic β-cells to function adequately across the adult life span, thus raising the trajectory for diabetes even before the baby is born.

Whatever Klotho's ultimate mechanism, the work raises the intriguing possibility that life span can be extended despite or perhaps via mild insulin resistance, a trait long considered deleterious to longevity.
