There are three ways to deal with this problem:

1> As Tanja shows on pic. one: Dress very carefully and VERY warm. Pile layer of clothing on layer of clothing and then put on your gloves and earwarmers..

2> As shown by Tanja: Drink ! Tea with rum, plain rum, or gluhwein will do nicely !!

3> As shown by our friend Wencke on pic. two: Keep moving !! Sadly, Wencke also put into practice step one AND two, which results in her skiing UPHILL in this picture. (note the people in the skilift, they move to the left....So does Wencke) No small wonder she didn't win the last-day-skiing-class-contest "No Wencke, The other way !!!"
