I’m in Sweden, it’s been snowing for two weeks now, reaching -20 and all the stuff, and I am happy. However, I can stop noticing that swedish guys at my department have no beards. All came perfectly shaved everyday, and take note that I am in an ecology department! My only explanation is that this is his quetzal tail. Only by showing that they have enough energy to bike for 30 minutes at -10 without the protection of a beard they have the possibility to find an appropriate mate. Things got that far that I am afraid that is becoming fixated at the population level, and his beards are becoming thinner. I plan to ignore the other alfa males this winter and show proudly my thick beard, even at expenses of my fitness.
