Santa needs to know a lot about reindeer and getting around the world.  Doc Santa Claus not only has a scientist background; he is an avid scholar of science, history, technology, reindeers, toys, elves, and of course, fairy dust magic.  

He loves to tell stories about his adventures throughout the world.  Most of all, Santa Claus tries to model kindness.  With modern technological magic, children can virtually visit with Santa Claus at the North Pole or have in-person visits to discuss Christmas wishes, tell stories, check the nice list, or simply to say hello.  And Santa Claus always loves to talk about all kinds of cookies, because he really loves to eat them.
