The former Finnish Posti, now Itella (stupid name, supposedly it sounds more "international") recently released its newest book of stamps. These stamps celebrate the sauna.
Allegedly a Finnish invention, the steam bath actually dates back to time immemorial. Perhaps the Finns were the first to reinvent the concept of the 3 room sauna (1 room for steam, 1 for washing, 1 for changing clothes), but in truth the Etruscans had that idea in use well before my Finnish ancestors even managed to move down to the ground from their homes in the treetops.
At any rate, sauna is an awesome and integral part of the Finnish culture.
