 We age, anybody can tell you, and I certainly can, our body begins to weaken. We can't do the things we could do when we were in our 20s. We can't do the things we could do when we were in our 30s or 40s. We slow down, we lose strength. We're just not quite as strong as we used to be. In a dead body, all the strength is gone. In fact, the body has been so weakened that it cannot even draw one breath of life.
