Solve for Happy

At times I thought the conclusions reached were not so scientific that Mo had liked. He's very particular about the science behind things, but I ended up feeling there were gaps in reasoning.
At other times I found the story to be moving and compelling. Finally I don't see the science necessarily being as necessary as the peacefulness one can achieve in the pursuit of happiness.

I found the epilogue to be especially touching. All in all, it was a great story.
