You’re assuming aging is bad for populations. My assumption is historical learning is valuable up until some percentage of your memories are false and/or obsolete. Even in a perfectly healthy individual both happen continuously. At some point an empty vessel has more utility than a trained up individual. So some heuristic that arbitrarily purges old people and their ideas is adaptive.
