Went skiing two weekends last month and there were "teletubbies" all over the hills!! It seemed that every other person had a block sticking out of their head.
I made a comment about what they used the footage for and one of the older teens told me that his Mom wanted him to wear it so if he happened to get killed, she would have the footage and know exactly what happened to him!! He was laughing about it and said that in the past 10 years, he had 8 broken bones, 2 cases of head trauma, 4 sprains, 7 different occasions of stitches. He was a snow-boarder during the winter and a skateboarder during warm weather.
