Santa, Rudolph, and Merry Christmas!

The final question about Santa Claus has to do with his girth. How can he deliver gifts all over the world in one night while being so heavy? Here’s something that we all need to understand: just because people are overweight, that doesn’t mean they can’t be fit.

Fat and fit? You better believe it. The problem is that we have so few heavy people who move into a high fitness category. But if they do, they can be fit according to a classic definition of fitness: the amount of oxygen used per kilogram of body weight per minute. Santa most likely qualifies; he must work out hard in the off season.

Would it be better to be leaner? Probably but remember, he’s a fictional character. I think we need to worry more about ourselves. But that’s a Memo for another time.

Rudolph’s Red Nose

I got a great question related to this week’s Christmas theme: why is Rudolph’s nose red? I couldn’t pretend to figure out that one, but wouldn’t you know it, someone else did. You can read about it in this news release from Johns Hopkins faculty and staff (1). They also diagnose the Grinch’s heart and explain how Scrooge could travel through time. The writing isn’t excessively scientific, so it might be something you could share with the older kids in your life who’ve grown skeptical about the magic of Christmas.

The Bottom Line

We hope you had fun with this week’s Memos. Health news can be overwhelming. As you prepare for this holiday, safe travels, and enjoy the time with family and friends. I’ll resume the Memos next Thursday with some ideas for your 2018 health goals.

From Paula and I, Merry Christmas, happy Kwanza, happy Dhanu Sankranti, we hope your Hanukkah was happy, a belated Happy Mawlid al-Nabi, and Happy Holidays to everyone! If we missed your holiday, let us know and we’ll be sure to include it next year. What’s important is that we all enjoy our holiday festivities and our family and friends, and we get to eat our special holiday foods.

What are you prepared to do today?
