When was the last time you listened to a sporting event on the radio? If given a choice between watching the game on a big screen HD or turning on the AM radio, most of us would probably choose the visual sensation of television.

But, for a moment, think about the active attention you need in order to listen to a radio broadcast and interpret the play-by-play announcer's descriptions. As you hear the words, your "mind's eye" paints the picture of the action so you can imagine the scene and situations. Your knowledge of the game, either from playing it or watching it for years helps you understand the narrative, the terms and the game's "lingo".

Stop eating all of that junk food.  Why?  So, you can live longer, of course.  Get off the La-Z-Boy and go run five miles.  Why?!  So, you can enjoy your old age.  No more drinking and smoking.  Why?!!  So, you can live to be 100 years old.

The rationale often given for converting to healthy habits has been to give you a longer life.  Who better to know about long lives than those that are closing in on the big 100.  The U.S. Census Bureau estimates there were nearly 425,000 people aged 95 and older living in the U.S. in 2010 − still only a small percentage of the 40 million U.S. adults 65 and over.

An athlete’s level of greatness is often measured by the opinions of his or her peers while they’re playing and especially when they retire.  Being recognized as one of the best by those who understand what it takes is rare.  This week, one of the world’s greatest soccer players of the last 30 years retired, yet he could walk down most streets in America without being recognized.  After 17 seasons, Paul Scholes of Manchester United played in his final tribute game last week and will become a coach at the club he’s been part of since his teens.

While not a household name in the U.S. like Messi or Ronaldo or Beckham, he has earned the respect of the greatest players of his time.

As Tiger Woods returns to action this weekend at the WGC-Bridgestone Invitational, mortal golfers wonder what's inside his head that makes him so much better than us. Well, chances are his brain actually has more gray matter than the average weekend duffer.

Researchers at the University of Zurich have found that expert golfers have a higher volume of the gray-colored, closely packed neuron cell bodies that are known to be involved with muscle control. The good news is that, like Tiger, golfers who start young and commit to years of practice can also grow their brains while their handicaps shrink.

For the crowd watching an Illinois high school football game last fall, it was a sickening feeling watching one of their Unity High School cornerbacks collapse to the ground after delivering a heads-down tackle on an opposing running back (see video here.) 

For Steven Broglio, an assistant professor of kinesiology at the University of Michigan, it was a mixed feeling of concern and curiosity as to the extent of the injury.  Since 2007, Broglio has been collecting data on the violent collisions that occur in high school football and their contribution to concussions and other head injuries.

Just as struggling calculus students wonder if they will ever actually use their new proof-finding skills in real life, developing athletes may be curious if their endless practice drills will ever serve them off the field or court?  Well, researchers at the University of Illinois have found at least one real life task that will benefit from an athlete’s unique cognitive abilities; crossing the street.
