37 Celsius is not very humid and hot, I can't believe that the Americans are complaining. Have they thought about those suffering from heat waves in Africa where the temperature is well above 45 Celsius. This is so typical of the Americans. Yes the young and the old do have the right to complain but those in the age range of 15 to 55 should be able to take the heat. Heat Stroke might not be common in America but around the world it is common. Seriously it is not that hot in America, think about the others countries near to the equator or even those in Africa and in Asia
