We went today skiing with the wife. I spent 1200 kcal of energy in one hour and a quarter, according to my Polar heart-rate monitor.

Afterwards, I felt tired. I hope this is not due to the vomiting sickness which is going around in the family, starting from our youngest daughter, transmitted from her kindergarten group. It may be caused by a norovirus, as the symptoms are very strong indeed.

Here are three photographs taken during the skiing excursion. As you can see, we are getting more and more snow almost continuously. The official "depth of snow" figure from the Helsinki-Vantaa airport nearby is 53 cm. That is a lot.

Update: Regarding the norovirus epidemic, there is a fascinating story in New Scientist, titled I, virus: Why you're only half human, referring to the fact that 34 percent of our genome are virus-like components.
