Sauna, Nakedness and Beer

Markham decided to use the hotel sauna yesterday to speed muscle recovery.  On Todd´s suggestion, he bought a cold beer and took it along, prepared for cool refresher on top of the unclothed European sauna experience.  A fellow hotel patron was already reclining in the heat, a large, SwissGerman speaking gentleman with generous body hair.  He bolted forward when Markham entered and exclaimed emphatically, "No beer!  Hot beer, no!"   Markham placed the beer outside the sauna and re-entered, to the gentleman`s satisfaction.

This has lead us to a number of theories.

1)  the man is a beer lover and objects to hot beer

2) cold beer would adversely change the microclimate of the sauna

3) beer would be too quickly absorbed by a sweaty body, leading to delirium

4) there is a rule that you take NOTHING but yourself into a Swiss sauna

5) the Swiss STILL do not have a sense of humor!
