There is no doubt that professors are very busy! We are often convinced about this fact by our professor Karel Prach who among all his obligations, teaching and writing of scientific articles does not forget about some joys. Before he left to France, he spent a couple of days with a world's leading expert on succession, Lars Walker. Their busy program included among others the oldest abandoned arable fields in the Czech Karst or Radovesice spoil heap. When we asked him to share some of their experiences with us, we received only a laconic reply: "We walk into the field, sit in pubs or work (we also sleep a little)... Greetings, K"
Difficult life, isn't it? :)
