When the NCAA canceled its Division I Men’s Basketball Tournament — also known as March Madness — it was only a matter of time until one group or another decided to come up with a substitute tournament, with brackets and all.

But we never could have guessed it would be for the ultimate stand-up comic.

The final round put Norm Macdonald up against Dave Chappelle, and Macdonald came out the winner, taking 53.49% of the 18,020 votes cast.

We owe a lot to the stand-ups. They deliver laughter that raises our spirits and dispels our stress.

And it seems that standing up and moving around starting first thing in the morning can do that for you too.

A new study in the journal Hypertension reveals that adding a 30-minute morning walk to an otherwise sedentary day helps obese people ages 55 to 80 lower their blood pressure.

Over three weeks, sedentary folks who did the rise-and-shine walk saw their systolic (top) number fall by an average of 3.4 points and their diastolic (bottom) number by as much as 1.6 points.

Those who added a pattern of standing up every 30 minutes and three minutes of light-intensity walking to the morning 30-minute walk saw their top number go down an average of 5.1 points and the lower number decline by up to 1.8.

In addition, women saw their levels of the stress hormone epinephrine decline by 12% to 13%.

Making these small changes to the daily pattern of inactivity can help protect against high blood pressure-related heart attack and stroke. And that's no laughing matter.
