{"product_id":"2940148368182","title":"What a Man of 45 Ought to Know","description":"The Periods of Seven Years in Human Life.—Ten of These Periods Make the Biblical \"Three-Score and Ten.\"—Intelligence Suited to Each Period.—Prevalent Ignorance Concerning the \"Change of Life\" in Men.—Sad Results of Such Ignorance.—Reasons for Change in Physical Life of Man Stated.\u003cbr\u003e\u003cbr\u003eHUMAN life seems to be divided into periods of about seven years. At seven years of age, the infant enters upon childhood; at fourteen, the boy enters upon manhood; at twenty-one, he enters upon the beginnings of the period of maturity. At the seventh period of seven years, or at forty-nine years of age, most men enter upon what has been aptly called \" the youth of old age,\" and at the end of ten of these periods of seven years, or at \" three-score years and ten,\" the Bible sets the allotted period of human life. The length of these periods is affected somewhat by the heredity, health, vitality and physical endurance of the individual. There are some who lack in physical endurance, or who mature early in life, and with such these periods may be somewhat shortened, while upon the other hand there are some whose splendid heredity, physical endowments, and temperate mode of life secure for them some lengthening of these periods. But, as we have said, these are about the average or normal periods of human life.\u003cbr\u003e\u003cbr\u003eWhat the infant should know when it has entered upon childhood, and has turned its face toward the developing years is told in the book in this series addressed to young boys, and that knowledge which is essential for the safeguarding of the purity and strength of those who have passed the period of puberty and have entered upon the years which lead up toward mature manhood, has been told in the book addressed to young men, and the in- formation necessary for those who have attained to years of maturity, and who look forward to marriage and paternity is told in the volume addressed to young husbands. To some it may seem strange that any added information should be necessary to men who have attained the years of middle life, yet our conferences with men between the ages of forty and fifty have developed the fact that men of forty-five are as ignorant of the important changes which have begun or are soon to take place in their bodies, as the boys who approach the period of fourteen are with reference to the changes which attend the transition from boyhood to manhood. If, in that important developing period for lack of knowledge, the young boy falls into vice, he measurably blights the strength and power of the years which lie before him. In like manner, if through lack of intelligence, at the period of middle life, the man fails to recognize the natural limitations of his powers, if he is unable to understand the changes through which his physical nature is passing, or fails to comprehend the revolution which is being wrought in the reproductive nature of his wife, he will be sure to suffer consequences which are far-reaching in their character.","brand":"New York, The Sterling Press","offers":[{"title":"Default Title","offer_id":47157866004720,"sku":"2940148368182","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940148368182_p0.jpg?v=1763701747","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940148368182","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
