A friend dentist once told me that if one has a tooth problem, it can have an effect on the way she/ speaks. Take this case of one sales agent. She had been bothered by one tooth which is in danger of falling off. Because of her work in the call center, she postpones her appointment with the dentist. Until one day, she accidentally bumped to the wall and out fell her tooth. Now she cannot speak well anymore, she really needs to see her dentist. No Internet Marketing Expert can be of help to her; it just goes to show that pre-planning is important in all things (on and off the internet).
