Obesity is less common at high altitudes because of the watershed. Environmental contaminants build up as water flows downhill and are in much higher concentrations as you approach sea level. 90% of the water I've drunk for the last 2 years has been either been bore water in the mountains, or rain water. It's had no impact on my weight,
