“Aging’s Escape Velocity and the Rabbit Imagine a sign far off in the future with a number on it that represents the age of your death. Every year that you live, you advance closer to the sign. When you reach the sign, you die. Now imagine a rabbit holding the sign and walking to the future. Every year that you live, the rabbit is half a year as far away. After a while, you will reach the rabbit and die. But what if the rabbit could walk at a pace of one year for every year of your life? You would never be able to catch the rabbit, and therefore you would never die. The speed at which the rabbit walks to the future is our technology. The more we advance technology and knowledge of our bodies, the faster we can make the rabbit walk. Aging’s escape velocity is the moment at which the rabbit walks at a pace of one year per year or faster, and we become immortal.”
