Anxiety and depression In the new study, Professor Andreas Meyer-Lindenberg of the University of Heidelberg in Germany scanned the brains of more than 50 healthy volunteers, who lived in a range of locations from rural areas to large cities, while they were engaged in difficult mental arithmetic tasks. The experiments were designed to make the groups of volunteers feel anxious about their performance.Professor Andreas Meyer-Lindenberg of the University of Heidelberg

6. The results, published in Nature, showed that the amygdala of participants who currently live in cities was over-active during stressful situations. "We know what the amygdala does; it's the danger- sensor of the brain and is therefore linked to anxiety and depression," said Meyer-Lindenberg.published in Nature

7. Blindness Only 20 per cent of youngsters play in the streets, therefore, lack of sunlight causes high myopia (severe short-sightedness). Half of sufferers become blind by middle- age.
