Viewers be warned that some pictures in this entry may be too explicit for young viewers, and apologies in advance if this it TMI, but for the purpose of full disclosure, you have to take the bad with the good. The knee on the viewer's left is the good one. The one on the right is obviously in not so good a shape. If not for the accident playing ice hockey last week and this poor result, we would be posting pictures of sunny mountains covered in snow. It's dumped a couple of feet of fresh powder this week across the Alps and the Jura, and the sun is out this morning, but alas, we will be taking a gentle stroll with the pudgy puppy instead of doing exotic experiments in gravity research.
