What about people, hardware (biology) and software (culture)? Our construction starts with an egg cell and a sperm cell that is 83,000 times smaller (in this phase the female is certainly cooperative). The 2 cells double, and double, 47 times (247) resulting in the 140.737 billion (1.4 * 1014) complex collaborating cells! Every day millions of cells die and the same number is re-formed. Usually we notice nothing of this "maintenance" (sometimes a cold, sometimes worse). In time, for example, we get hungry and then we become saturated, or there is a sense of movement. All essential nutrients and processes are thus guaranteed. Our body never gets older than 10 years! In the colomn it is argued that we exist in interaction rather than in content.
