1 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. 2 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.
3 You have the best physical sense of yourself from 15 to 24; the best professional sense from 40
to 49.
Before the age of 24, we believe that our happiest years are yet to come；over 30, we believe that they
are behind us. 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.
4 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 5
