Boredom?
Yes, the fact that life span remained the same is significant.
Since the study was to see if death came later, I thought the cause of death
would somehow be important. It would seem that in a study such as this,
saying "I dunno, they just up 'n died" ignores an important piece of
information. Did they all explode? Did they write tiny suicide notes? That
would give credence to the boredom theory ;-) Did any of them develop
cancer?
