请认真阅读下面短文，并根据所读内容在文章后表格中的空格里填上最恰当的单词。注意：每空格1个单词。
The ups and downs of life may seem to have no predictable plan. But scientists know there are very definite patterns that almost all people share. Even if you’ve passed some of your “prime”, you still have other prime years to experience in the future. Certain important primes seem to peak later in life. It is really good news to many of us who don’t have a good feeling about ourselves now. We needn’t be worried about it now. When are you smartest? From 18-25, according to IQ scores; but you’re wiser and more experienced with increasing age.
You’re sharpest in your 20’s; around 30, memory begins to decline. But your IQ for other tasks climbs. Your vocabulary at the age of 45, for example, is three times as great as when you graduated from college. At the age of 60, your brain possesses almost four times as much information as it did at the age of 21. It is really amazing, but it is true.
When are you happiest? You have the best physical sense of yourself from 15 to 24; the best professional sense from 40 to 49.
Before age 24, we believe that our happiest years are yet to come; over 30, we believe that they’re behind us.
When are you most creative? Generally between 30 and 39, but the peak varies with different professions.
Mozart wrote a symphony and four sonatas by age eight, and Mendelssohn composed his best known 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 prizewinners did their top research in their late 20’s and 30’s — creative people continue to produce quality work throughout their lives. For the “well-conditional mind”, there is no upper limit.
So if you are not very successful at present, it really doesn’t matter. Just have a little patience and wait for your best time.
