Those of us who can’t get off the couch to put on our running shoes, so we can walk the three feet to the kitchen to refill the bowl witih cheez its, don’t have to worry about the effect of limited exercise and our hearts. According to a new study, we should brush our teeth to reduce heart disease. And I thought I’d have to renew my membership to the gym. Writing a check to the gym once a month is all the exercise I can manage. The bacteria associated with periodontitis is also associated with cardiovascular disease. What I’d like to know is do I have to brush twice or is once be enough to thwart off heart disease? Maybe I can brush from the couch. The bathroom is all the way upstairs.
