Guess what? After a few hours, all the blood in the body goes to the lowest spot. Then after about 12-15 hours rigor mortis sets in, then, after about another day, bloating and distention occurs, the body becomes freakishly large, due to all them bacteria and crap that are eating all the insides up and expelling gas and all that other nasty stuff. Of course, well before this disgusting stage, the body (figure on about 160 lbs of meat) starts to smell, bad, real bad, so bad that anyone within about 30 or so feet would say "Damn, what the hell is that terrible smell? It smells like a dead person who is distended and rotting away?"

Maybe they were keeping the office real cold to conserve energy. It is Finland, after all.
I've been to Europe. Everyone there stinks.
