On my quest, I’ve wound my way left and right and had days when I wanted to give up. But I’ve persevered. Along the way, I have seen a lot of tributaries, but I’ve also found what may be the spring. In the coming pages, I will present a new idea about why aging evolved and how it fits into what I call the Information Theory of Aging. I will also tell you why I have come to see aging as a disease—the most common disease—one that not only can but should be aggressively treated. That’s part I.
