__71__ From 18－25, according to I．Q. scores；but you are wiser and more experienced with increasing age.
You are smartest in your 20's; around 30, your memory begins to go down, particularly your ability to perform mathematical computations. __72__ Your vocabulary at the age of 45, for example, is three times as great as when you graduated from college. At 60, your brain possesses almost four times as much information as it did at the age of 21.
__73__ You have the best physical sense of yourself from 15 to 24; the best professional sense from 40 to 49.

A National Health survey agrees: after the age of 30, we become more realistic and do not view happiness as a goal in itself. If we maintain our health, achieve professional and emotional goals, happiness, we feel, will follow.
__74__ Generally between 30 and 39，but the peak(顶峰) varies with different professions.
Mosart wrote a symphony (交响曲) and four sonatas by the age of 8, and Mendelssohn composed his bestknown work A Midsummer Night's Dream, at 17, but most of the great music was written by men between 33 and 39.
Though the peak in most fields comes early, most Nobel Prize winners did their top research in their late 20's and 30's—creative people continue to produce work with high quality throughout their lives __75__

D. Do you know what I．Q. refers to?
E. But your I．Q. for other tasks goes up.
