Aging is a biological process that no one can avoid. Ideally, growing old should be a time to relax and enjoy the fruits of your labor. Aging also has a darker side, however, often linked to disease.

Every second, your cells perform billions of biochemical reactions that fuel essential functions for life, forming a highly interconnected metabolic network. This network enables cells to grow, proliferate and repair themselves, and its disruption can drive the aging process.
