Whether you’re a professional athlete or a parent just trying to keep an active child safe, concussions are a growing concern these days. Post-concussion problems endured by football players and other brain injury survivors are not new.  However, concussions sustained by local hockey wonderkid Sidney Crosby have brought more attention to the potential danger of head injuries over the past year.

1.  The top and bottom parts of  a woodpecker’s beak are uneven in length, and the longer bottom beak deflects force away from the bird’s brain on impact.

2.  Unlike us, the woodpecker brain is encased in spongy plate-like bones.  These are arranged unevenly around the brain and leave no space between the brain and skull.

3.  A seatbelt-like hyoid bone connects the beak to the skull where it then surrounds the brain.

Together, these factors ensure that the woodpecker’s brain is affected as little as possible  by the constant impact of head banging. 

Unfortunately, even if these factors were incorporated into the design of sports safety helmets, there is no way to get around the fact that human brains are separated from our skulls by a gap that is non-existent in woodpeckers.   And it’s the motion of the brain within this space that would still remain a factor in potential injuries.

So, unless you’re a woodpecker, the best way to avoid head banging injury to your brain is to not bang it in the first place.

Twilight reveals the silhouettes of things that are often hidden in complete darkness or light.  Suddenly, that which is commonplace and overlooked becomes apparent. The light at this time of day offers both mystery and revelation.

One way to understand something better is to look at its opposite.  Exploring negative space and color negatives in art can reveal how we look at subjects in their relation to the space around them.  So often we allow ourselves to be distracted by familiar colors and arrangements. By looking at negatives, lines and shapes become apparent that are sometimes hidden in plain view.  Likewise in human nature, who your enemies are may indeed reveal more about you than the company you keep.

It’s fascinating how familiar elements in nature still have much so much to teach us about beauty, design and ourselves.  All we have to do is open our eyes.

In the right light, at the right time, everything is extraordinary.
