His personal habits more naughty than nice, public health expert says Is Santa Claus really public health enemy No. 1?

Jolly Old St. Nick promotes obesity, drunken driving, speeding and general unhealthy habits, Dr. Nathan Grills of Monash University in Melbourne contends.

And the guy in red and white should walk or ride a bike instead of traveling at breakneck speed in his sleigh everywhere.
