Biological Imperative

Some people think it's terrible that we are, to one degree or another, slaves to our genes, but maybe it's wonderful. Morality is sticky and confusing, but nature in all its wildness and cruelty is orderly and beautiful. (And also awful, yes.) So we humans have our lives. We tend to resent our natural phases, wanting to be at some other stage of life. But isn't it kind of nice to have at least a few chemical signals telling us what to do? Isn't that why we marvel at the birds and cats and trees? I mean, they know what to do! All the time!
