Those idiots dont 'give up' until they lose a kidney or end up with a life threatening disease..but then again there are the brainless ones who go back to their old habbits as soon as they feel 'ok' again.
Like another Finnish, Marko Savolainen, who is currently training for pro competition at 2013. He has reckon that it is smart thing to try to reach at the 10-15Th place with the prize of his new kidney. His peak was 1997 - 2001, then he got addiction to amphetamine, after that he hasn't be in competition, has lost his kidneys, drop his body weight to 171lb (78kilos), and now at the age of 40 years he try to make comeback. He has his place as a local living legend, and now he try to be even more, but may end up back in to dialysis. What a smart guy.
