I came across this article with high hopes that it might have some useful analysis, but it is based on the view that the goal of life is ataraxia, so it focuses on whether it is necessary to spend more than a moment in ataraxia in order to have a full life, rather than a more helpful analysis.
(Another example of how to chase rabbits through "ataraxia" rather than focusing on pleasure as the goal)
Nevertheless it seems to contain some good research for someone looking into the issue.
