A very thought-provoking article...
"As modern evolutionary biologists increasingly recognize, bodies are our genes' way of projecting themselves into the future. Bodies are temporary, ephemeral, short-lived apparatuses for those genes, which are the only entities that persist over evolutionary time. No matter how much money, time, or effort is lavished on bodies, regardless of how much they are exercised, pampered, or monitored for bad cholesterol, they don't have much of a future. In the scheme of things, they are as ephemeral as a spring day, a flower's petal, a gust of wind. What does persist are genes. Bodies go the way of all flesh: ashes to ashes, and atom to atom. Genes, on the other hand, are potentially immortal."
