You can spend your lifetime trying to understand the science of nature. Technology has even succeeded in a crude imitation of life through cloning. Soon, we will harness nano-technology and artificial intelligence. Every step toward understanding nature reveals more clearly that science will never explain the meaning of life. It is a race that can't be won, a journey without end, and a search without a rescue.
Point is, nothing lasts forever.
For that matter, nothing lasts very long. But the meaning of life doesn't lie in records and reputations. It's in the pursuit of fulfilling God-given talents. Whether your gifts are suited to philosophy, baseball, archaeology, or skiing, your challenge is to explore their limits. A steroid-bloated Ben Johnson running the 100 meters in like 9 or 10 seconds.
