I now own a couple of books about melatonin, which I started to buy 1 ½ year ago, after my wife then went to the hospital and there told them about her problem with not getting enough sleep. Of “course”, the doctor did not tell her about melatonin but instead put her on sleeping drugs.But as we have been told, or read, again and again have been told, in the body we have the natural sleeping hormone melatonin, so therefor, instead, I went on searching after books about melatonin; I like more to read in books than in Google.And then, especially by reading this book, and besides the one written by Jeff T. Bowles.: “Extrem Dosiert! Melatonin, Das Wunder”, I have learned how important the hormone melatonin actually is for much more than just sleeping. That is how melatonin is working when managing other hormones in starting their works. However, beside this I especially have realized the connection between melatonin and our aging. That is how the production in the body, of melatonin, turns down while we are getter older, and this decease of melatonin so further increase our aging.In the book, concerning this age related connection to melatonin, we clearly see it proved by the many mice experiments, which we reads about. Experimentations in which we learn about how old mice actually gets younger, in the wat they live, and besides are living longer, equally for up to 25 years, if translated into human years, when their pineal glands are replaced with pineal gland’s from young mice. And after this, then how the quit opposite goes on, when young mice got their pineal glands changed to old pineal glands.Therefore, after these cases we realize how important it is to try to, during the life, to keep our body’s, our bloods, amount of melatonin, equal to what it was were in the age of the twenties.And in the book, besides the connection between melatonin, and how old we will be, we also learn about the connection between low melatonin in the body, and the thereby related increased amount of diseases; and thereby resulted shorter life.Daily we are told, and in new books still read, that in the body, in the nighttime, 90% of the melatonin is produced, while only 10% during daylight. Moreover, the doctor in the hospital told me the same as late as in February this year. However, here in the book, printed 23 years ago, there we read that this is wrong. Because after we have passed the 20es of age, then the production in nighttime starts to decline! But concerning how much it decline, I more will trust what I, 2 months ago, then read in the Jeff T. Bowles book, which I mentioned, because that book was printed last year. And there we read about a much harder decline, than in “The Melatonin Miracle” book, that is the melatonin production, actually by the age of 70, then the production in the darkness now only is the same as the production in the daylight, that is, now 10% and 10%.As a remark, on the side 114 we read about how a cancer specialist named K. W. Starr, nearly five decades before the book was printed, then had reported about the successfully use of melatonin to control the sarcoma, one of the worst types of cancer. Actually back in 1952, then Hoffer told about how 40 grams/day of C vitamin then cured a patient for this cancer, and who then lived 20 years after being cured.As another remark. My edition of the book was printed 23 years ago, and I think that if it now was reprinted, then they the writing about cholesterol would be changed. Because, for example, on the side 206, there we read about a connection between high cholesterol and heart attack. And much has changed during these past 23 years. Even now way back in February this year, the doctor in the hospital now talked about how good cholesterol is. Which I until then had been fight against the doctors about since February nine years ago, when my wife then was measured with a “high”, but not too high according to what Harvard Medical School already back then was writing.Finally, again I will call this the best book about melatonin, which I have read, but the knowledge will increase when connected to the book written by Jeff T. Bowles.
