There are just a few weeks to go before Santa makes his way from the North Pole and to the homes and down the chimneys of all good little girls and boys. Santa does an awful lot of work in such a short period of time. And what about all of the cookies he eats and the milk he drinks, will that slow him down? Is Santa Claus fit and ready for the ride?

A UNC cardiologist, geneticist, psychologist, endocrinologist, and Santa's very own family physician weigh in.
