When Antanas Mockus, the former mayor of Bogota and the Green party candidate for Colombian presidency in the coming elections, announced he suffered from Parkinson's disease, everybody here thought his chances to win were over.
But they were not. In fact, they increased.
This eccentric university professor is running 10 points behind in latest opinion polls from Juan Manuel Santos, the former minister of defence and mega millionaire who has vowed to continue with President Alvaro Uribe's fight against the Revolutionary Armed Forces of Colombia (Farc).
Mockus managed to cut the murder rate in Bogota during his two terms as mayor and has the clean image that, in many circles here, the government lacks. And that, it seems, is his greatest strength.
