A friendly smile

I get a tip-of-the-day kind of thing in my e-mail. Here's what I got today:

"In a recent study, people who had at least one close friend appeared to have as much as a 30 percent lower risk of periodontitis, a dental disorder that can lead to tooth loss. Researchers speculate that the connection may be due to the stress-reduction benefits that friends offer; stress is associated with poor oral hygiene."

Thanks friend, for doing things neither of us realized. :)
