Changing one's duties based on age is a habit found in different types of social insects, such as bees, wasps and ants. Generally, older individuals take on the most dangerous tasks to protect young people. But the surprising thing is that, according to the results of a recent study on ants, these small insects are aware not only of their age, but also of their health conditions. In fact, the research group of Dawid Moron, of the Jagiellonian University in Poland, observing for five weeks the ants of eleven colonies recreated in the laboratory, showed that the individuals to whom life expectancy had been artificially reduced (identified with a dot of colored paint) they ventured further and further from the nest in search of food. Not only that: they were probably able to "measure" their life expectancy regardless of age, since the ants that were in the worst state of health took on increasingly dangerous tasks, just as if they could foresee that, much, they still had little to live on.
