There it was again, the noise in my head getting all out of focus. The type of noise that you hear in the movies when someone is paralysed, suffocated, the one that you hear at the hospital when a heart stops beating. I knew what I needed: high altitude. I buy a flight to the highest capital city in the world: La Paz, Bolivia, at an elevation of 3,650m above sea level. The city is located in a bowl-like depression surrounded by the high mountains of the Altiplano. Overlooking the city is the towering, triple-peaked Illimani. Mountains are the true stairway to heaven and the ones that discover this cannot resist the temptation to get back on track, back to the wild, back to the calm of a quiet night by the fire.
