I totally agree, that's why life experiences have taught me to never anticipate or expect anything. Of course then, life is continuously surprising one with good and bad things, but the real life skill to be learned by humans, IMHO, is to live life in the moment and handle things as they come along. When you've accomplished that, then you slowly come to realize that life resembles a very strange joke, so I've also learned to laugh at it and myself a lot over the years.
I also read this study and to me it is just common sense. Our minds and bodies are wondrous devices that are designed to support our spiritual existence, if we allow them to.
