No, not the pink stuff in a can. I'm talking about the vile stuff that floods your inbox.
Canadian researchers split a group of 2,100 into two groups and spammed one of them from 12 weeks with emails promoting health lifestyles and motivational messages. The result - those who received messages about good diet and physical activity saw their mean body mass index (BMI) go down, meaning it improved.
Now, I'm not sure I can support the claim that spam is good for you, as the writer of the article contends (and I parroted in my title). I think this shows that conditioning and reinforcement can come from unexpected places.
