Every year, many of us vow to eat right, exercise, stop smoking, or lose that extra weight.

Children have a definite schedule for vaccinations, and in most states, children must have proof of immunizations to enter school. With the exception of health care workers and college students, there are no requirements for adults. It’s up to us.
