Aging and energy


It's a nearly universal lament of people over age 35: They don't have as much energy as they did when they were younger. One of the most common complaints is that they can't stay up as late as they once did and still function normally the next day. People also notice that they're not as strong as they used to be or that their muscles don't move as quickly.
