WMD: The man is a legendary party animal:
'Eight years later, at the olympiad in Buenos Aires in 1978, I broke my leg during a party in Heikki's hotel room, which taught me that moderate drinking during a stressful tournament may be alright, but that one shouldn't try to keep up with the Finnish.
'The party went on, while I was lying on the floor, unable to move. One of the merrymakers still had the presence of mind to call the captain of the Dutch team Frans Kuijpers, who had gone to sleep much earlier, but immediately came to rescue me. He knocked at the door and was let in by Heikki, who said: “Of course it is terrible what happened here, but what do you want to drink?” First things first.'
