You’ve seen it. Two people the same age — one looks and functions a decade younger than the other. One is energetic, recovering quickly, rarely ill. The other is managing a growing list of health issues, running low on energy, feeling the weight of their years. The conventional explanation is genetics. Some people are just … Read more
Sleep is when your body does most of its maintenance work. Most people know this in a general way — you feel better after a good night’s sleep, worse after a bad one. But the cellular specifics of what happens during sleep explain why it’s not just about feeling rested. It’s about whether your cells … Read more

It has to do with a specific class of molecules your body produces inside every cell — molecules so fundamental to how your body works that when their production declines, almost everything else is affected.
