I'm not a malicious person. When you get past the tattoos and leather, I give people a fair shake. There are periods when I've sowed some wild oats, no doubt about it. And I can party with some of the heavyweights. There are some stories about me that, yeah, where there's smoke there's fire. But sometimes the smoke is just smoke.

The plumbing and pluvial dynamics of the Amazon, the largest freshwater system on Earth, are still far from understood. This is partly because it is a semi-open system. Moisture flows in and out unpredictably. A lot of nonlinear feedback loops and 'remote influences' - continental, transcontinental, oceanic, meteorological - come into play.
