   The weather can also influence intelligence.For example，in a 1983 report by scientists，the IQ of a group of students was very high when a very strong wind came，but after the strong wind，their IQ was 10% lower.The wind can help people have higher intelligence.Very hot weather，on the other hand，can make it lower.Students in many schools in the United States often get worse on exams in the hot months of the year （July and August）.
   Weather also has a strong influence on people's feelings.Winter may be a bad time for thin people.They usually feel cold during these months.They might feel unhappy during cold weather，too.But fat people may have a hard time in hot summer.At about 18℃，people become stronger.
