let them eat spam

Curious report in the Sun-Herald today (no link):

"Email spam can be good for you if it comes as a steady stream of emails nagging about healthy habits, Canadian researchers have concluded. People who were spammed about healthy eating and keeping active tended to exercise and lose weight, researchers at the University of Alberbta found. The 12-week study involved 2598 workers."

So presumably those who were spammed about Viagra... bonked more?
