It is surprising that science simply proves what we should have known all along, like how we should be attracted to people by smell and taste. But they do tell us why. When we're attracted to people by smell and taste, we're looking for people who have different immune systems, which will result in babies with strong immune systems.

It's funny. When I look out for you, there is nothing for me to find. And when I give up, you suddenly place things there.
