While you're at it, when was the last time you had your cholesterol checked, teeth cleaned, or a general workup from your PCP? If you answered, "It has been a while," to any of those questions, you might want to make some appointments. With some insurance companies, preventative health exams are free (no copay). If you don't have insurance, you might contact your local hospital to see if they offer any testing in the community. Covenant Health, for instance, has offered cholesterol and blood glucose checks for around $10-$20.
