this is the post i liked so far.... i completely agree with all above views... still i don't know... why all houses are brown color even plenty of colors available in shops. some times expensive land cruisers also with brown paint on the road. for hair fall, the climatic air in qatar is fully polluted by chemical gases due to petro industries are very near (mesaieed) to the residential areas not more than 50km is the great cause. greenery is not enough to consume the gases and fumes. good thing in qatar, when your car stopped in the high way, many people especially youg men are trying to stop their cars and ready to help include police men. i experienced whenever my car tire got puncture. only we can do here is enjoy the difference with rest of the world. cheers..!!!
