More than a billion adults worldwide are now overweight - and at least 300 million of them are clinically obese. Childhood obesity is already epidemic in some areas and on the rise in others. Worldwide, an estimated 17.6 million children under five are said to be overweight.

I think people need to see on both sides. Seeing how the people in the Palestinian Territories can't move around - it's a maze now, with the wall, the road blocks and everything else. It takes you hours to get from one person's house to your job or to a friend or even to the hospital if someone's hurt. Then you go into Israel and see in Tel Aviv, where they have 12-18 bomb threats a day, which are real. It completely disrupts their life. Or Sderot where bombs are falling daily from the sky fired by Hamas militants in the Gaza Strip.
