I read lots of geeky blogs - BoingBoing being one of them. They posted this article today about a study done that's to be released in "Psychiatry Research: Neuroimaging" that shows that Meditation has measurable effects on the brain.
This is a link to the Study: http://www.physorg.com/news/2011-01-mindfulness-meditation-brain-weeks.html
Meditation, while maybe not a common practice for most people, is certainly socially acceptable, and part of the common continuum of healthy practices.
What if we called Karezza "Partner Meditation" - could we get a scientist to spare some time on an MRI machine to study the effects? We can dream, can't we?
But it seems more likely that a scientist could get some time on an MRI machine to study the brain before getting addicted to something like Porn (or Farmville!) and then what it looks like to recover from that addiction.
