Passage One The ups and downs of life may seem tohave no predictable plan. But scientists now know there are very definite lifepatterns that almost all people share. Today, when we live 20 years longer thanour great-grandparents, and when women mysteriously outlive men by seven years,it is clearer than ever that the "game of life" is really a game oftrade-offs. As we age, we trade strength for ingenuity, speed for thoroughness,and passion for reason. These exchanges may not always seem fair, but at everyage there are some advantages. So it is reassuring to note that even if you'vepassed some of your "prime", you still have other prime years toexperience in the future. Certain important primes seem to peak later in time. WHEN ARE YOU HEALTHIEST? For men, from 15to 25; for women 15 to 30 "A man is in his best shape in thedecade before age 25," says New York internist Dr. Donald Tomkins."His muscles are firmest, his resistance to colds and infections ishighest, and his body is most efficient in utilizing nutrients. "Women, forreasons scientists do not understand, get a five-year bonus. Peak health beginsto decline when the body process called anabolism(cell growth) is overtaken by theopposite process, catabolism (cell death.) "Cells have been dying sincebirth," says Tomkins, "but in our late 20's, they start dying fasterthan they are replaced." Also, muscle is replaced with fat. Women also get an additional bonus ofgood health later in life. The figures of National Institute of Health showthat the onset of such "old age" diseases as arthritis, rheumatism,and heart ailments denies the generally greater fitness of women: Lifeexpectancy for men is now 68.3; for women 75.9. U.S. aging authority WilliamKannel says, "Older women with low blood pressure are practicallyimportant." However, psychologists believe that by entering the competitivejob market in increasing numbers, women may eventually give up theirstatistical advantage. WHEN ARE YOU MOST CREATIVE? Generallybetween 30 to 39, but the peak varies with different professions. Mozart wrote a symphony and four sonatasby age eight, and Mendelssohn composed his best-known work, A Midsummer Night'sDream, at 17. Psychologist H. C. Lehman presents the years for peak work inmany fields. Though the peak in most fields comes early--most Nobel Prizewinners did their top research in their late 20's and 30's-creative peoplecontinue to produce quality work throughout their lives.
