A few weeks ago=2C Bob Fournier was talking about this on CBC Information M=
orning's Wednesday science slot. He said there is some peripheral interest =
in woodpecker research related to concussion prevention and helmet design f=
or sports. The trick would be to come up with a structure that worked for a=
 wide range of points of impact. This might be possible with modern materia=
ls and technologies.
