Outdoor vs. Indoor Lifestyle

photo was sent to me by S., a document from his latest trip in the Alps, Europe, discovering the silence of the DRACHENSEE (= dragon lake), taking the risk to meet a dragon. So whereas one of my dearest relatives had his outdoor challenge, I permanently stay at home playing guitar

P.S.:
another version of comparing the outdoor / indoor lifestyle:
the German movie (and novel) “Die Vermessung der Welt” (book: Daniel Kehlmann; movie: Detlev Buck)
comparing there: Alexander von Humboldt (outdoor, 1769-1859) and Carl Friedrich Gauß (indoor, 1777-1855)
