Unit 17 Laughter The ups and downs of life may seem to have no predictable plan. But scientists now know there are very definite patterns that almost all people share.

From 18-25, according to I.Q. scores; but youre wiser and more experienced with increasing age. Youre sharpest in your 20s; around 30, memory begins to decline, particularly your ability to perform mathematical computations. But your I.Q. for other tasks climbs.

A National Health Survey agrees: After age 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, then happiness, we feel, will follow. When are you most creative? Generally between 30 and 39, but the peak varies with different professions. 你的身体感觉最好；40岁至49岁之间你对自己的职业感觉最佳。24岁之前，我们相信自己最快乐的日子尚未到来；过了30岁，我们就认为最快乐的时光已逝去。一项全国性的健康调查也验证了同样的结果：30岁过后，我们变得更加实
