Since honeybees are the original “hive mind,” what can we learn from these social insects?

Thomas Seeley is the Horace White Professor in Biology at Cornell University. He is based in the Department of Neurobiology and Behavior, where he teaches courses on animal behavior and does research on the behavior and social life of honey bees. He is the author of Honeybee Ecology (1985), The Wisdom of the Hive (1995), and Honeybee Democracy (2010).

Death may be inevitable. But what about aging? If we could figure out what biological switches get flipped to start the process of decline, could we reverse it? Even prevent it?
