For a more in depth treatment of anti-fragility. Read anti-fragility a couple of times. One of the one most important ideas of our time (IMO). Btw, your intuitive linking of "age degradation" is also pointed out by Taleb albeit in a different manner. His premise is that ideas that have persisted for a long time are anti-fragile. This is because they have been subjected to shocks, to ridicule, to experimentation and these ideas have become better. Age of existence is one of many indicators of anti-fragility.
