WHAT LIFE AHEAD IS and DOES
Abstract: Life Ahead - a new computer program provided as a free download by its author - shows how most middle age people probably can gain 15-16 or more years of healthy life from acceptable changes in lifestyles. The program identifies the user's levels of more than 50 key health factors including the levels of 20 key nutrients in each entered diet, and compares these with values needed for best long range health. It then shows the specific things that must be done to achieve best health, and how much benefit the change in each action can produce. This type of analysis is not achievable today without use of a sophisticated computer program. Life Ahead based on objective and state-of-art analyses of all of the useful major research found on included health factors provides this new and much needed program.
The Life Ahead Program: The major diseases that terminate the lives of 75% of people in the US today are atherosclerosis and cardiovascular diseases, and cancer. Tens of thousands of research studies are published each year on risks of these major diseases. Much of this includes information that used properly could prolong and improve our future lives. But we face two problems. First, we are overwhelmed by the many things we are supposed to do. Second, it is near impossible to know which of this advice is of major importance, and which is trivia
Life Ahead computes how risk of major diseases can develop or regress at each age of life as a result of various influencing factors. A user first answers questions about foods eaten, certain measurements such as blood pressures, past cholesterol values, diet supplements taken, usual exercise and other life habits. Life Ahead then develops the WELL-DAYS, or the number of future days alive and free of major disease a population of people having these identified habits and health factors probably will enjoy.
Life Ahead next selects the usually acceptable changes in habits that can slow down the progress of these killer diseases. Key new capabilities of Life Ahead include its new and more detailed health analysis of the importance of up to 20 different nutrients in diets and diet supplements, and of it analysis of benefits of each kind and amount of exercise. It then re-computes and displays the reductions in risk of each disease and the likely added Well-Days of life that will result from each habit change. A user can then view the specific actions needed to obtain the improvement in Well-Days possible that often will total to 15 or more years of potential healthful life. Life Ahead often can suggest how risk of heart disease can be reduced by more than ten times. Or how risk of cancer can be reduced four times. The analysis can warn some users of a 95% likelihood of a heart attack as soon as within the next ten years.
But although we probably can forecast the Well-Days average for a population of individuals for any combination of health factors, some individuals will do better and some will do worse than that of the average population. It is impossible to forecast the exact health problems that each individual may face. Even so, it still remains likely that a computed gain or loss in Well-Days for a change in habits still will provide a useful index of the potential change in future health for most people. And this can guide us to take those actions that will produce best long range benefit.
Life Ahead Uses Global Analysis: We are barraged today with advice from health studies. Each tells us we should be doing this, or argues that what was advised before is no longer true. Rarely mentioned is that nearly all of these health studies have very wide margins of error, or that a third to a fourth of studies on most subjects often produce results that disagree. Despite much time, cost and researcher expertise, it is very difficult to obtain truly valid information from individual research studies of groups of people.
Global analysis of health research solves this. First is produces an objective analysis of ALL or nearly all of the available useful research data found to date on a given factor in all studies found. With results usually from a dozen or 50 or more studies this usually removes the problem of individual study error. Second, Global Analysis analyzes major diseases not just as statistics but as biochemical processes that proceed slowly but destructively throughout life. It aims to identify how much our specific health actions can speed up or slow down these unwanted biochemical processes. A Global Analysis quantifies with use of engineering methods how much a given health action can reduce or increase the risk of major diseases at every age, and how much such an action can change the length of our healthy life. This provides a more comprehensive and accurate method than that possible using just the statistical factors from individual studies. .
Life Ahead opens up a entire new window of knowledge. We are told that we should eat more and less of specific things. But no useful method for estimating how different diets and foods can determine progress and risk of major disease and extend lives has been available. There has been much talk about antioxidants that are supposed to reduce the risks of heart disease and cancer. Yet there has been no way for knowing how much antioxidant is needed from foods and supplements in a diet to produce a maximum desirable protection against these major diseases. We are admonished to "Exercise more." But way for estimating how different kinds and amounts of exercise can produce the cardiofitness that can substantially reduce risk of these diseases has been recognized. The Global Analyses used to develop Life Ahead provides solutions to each of these problems.
About Health Models and some History: A first version of the Life Ahead Model that analyzed exercise and cardiovascular diseases globally was developed from a seven-year project during 1975 to 1982. This model was described in Proceedings of the 19th Annual Meeting of the Society for Prospective Medicine, pp 52-61, and was a basis for a book - The Pulse Point Plan, Random House, NY (1982) by this author, Forrest H. Blanding. The book was reviewed and introduced by the top world authority on exercise and disease Dr. Samuel M. Fox. Thus this book and its appendix detail provides a scientifically based and reviewed reference. The findings in that book on cardiofitness, exercise and cholesterol that then were highly controversial have been confirmed repeatedly and near precisely by research published since that is shown on this website. This new Life Ahead version - a new ten year project - provides a vast advance over that first Life Ahead. (A few copies of this earlier now out-of-print but still relevant book can be made available)
Many computer models have been developed and are in use. Some are useful Health Risk Appraisals that have helped millions of people become more aware of some potential health problems. Others that show how many years you can gain from trivia as brushing your teeth can be pure mathematical trash. Because most past computer models provide little or no documentation of how they were developed it is difficult to assess just how meaningful are their results. Life Ahead often shows many of the same QUALITATIVE effects of health factors as those found from health studies, risk factor statistics or from other health models. For example, it shows the same general harm long known for high blood pressures, LDL cholesterol and smoking. It shows the long known beneficial dietary effects for eating fish and fruits and doing exercise, and the negative effects of too much dietary meat and fats.
The new contribution of the Engineering based and Life Cycle method of Life Ahead is the extensive QUANTIFICATION of the benefits of life style habits. For example, conventional health advice variously suggests "Everyone should walk a mile, or 30 minutes, or 60 minutes each day." Life Ahead identifies how different kinds and amounts and intensity levels of walking and other exercise can produce a trivial 10% or a ten times reduction in heart disease; how different diets can lose or gain 5 years of Well-Days or accomplish little; or when and how specific diet supplements can produce a major benefit or no benefit. This new quantification shows that multiple life habits and factors combined with diet can have a far larger effect on our Well-Day s of life than previously has been realized. Because of the many new findings of Life Ahead, it was felt important to describe in detail how the program was constructed and to document the extensive research used in its development. Many of the actual formulas now used in Life Ahead are provided in the accompanying Health Research Library.
The Life Ahead Health Research Library on this website provides tables of the actual data from hundreds of key research studies that often include all useful research found published on a factor. This should improve confidence in the model results, and provide assurance that the program was based on a serious and objective analysis of the available research. Second, this will permit not only researchers and doctors but any individual with a scientific or engineering background to examine conveniently the results of major research on each risk factor. Much of this research has not previously been brought together in a consistent format and adequately analyzed. (See "Understanding Health Research"). The sum total of now available actual research that mostly seems to have been overlooked can provide devastatingly strong evidence about the importance of factors such as vitamins, diet and diet supplements and cardio effective exercise. It is hoped that this documentation will stimulate researchers and others to identify any bugs and more basic problems found with the present model, and contribute more research studies, data and constructive ideas that could lead to its improvement.
Looking Toward the Future: Despite two decades of development, the present model still provides only an approximate quantification of how major diseases develop as result of potentially predictable chemical processes. Life Ahead is believed to be the first documented model of this type. But some included factors as for example the effect on disease of body weight are still quantified only at the statistical level. Ultimately, teams of biochemists, physical scientists and biochemical engineers should replace the present and approximate macro-quantitative BioChemical processes used in this Life Ahead with more detailed biochemical process kinetics. More knowledge about DNA should improve the family history factors that today involve a major potential error component in forecasting the health risk of individuals. Life Ahead also should be expanded to include more of the key life-destroying diseases and other diseases that diminish quality of life. It is hoped that others will initiate the development of more and better Global Analyses that move knowledge further beyond the dull statistics of so much of todays health research. Ideas received will be acknowledged and given careful consideration and worthwhile improvements will incorporated into the model.
About Publication and 'Peer' Review: Most health research is in form of individual research studies that produce specific data. Articles rarely take more than a dozen journal pages of space, and normally are for a single defined subject and are 'peer reviewed' before publication by two or more persons knowledgeable in the same field. Life Ahead includes not only an extensive computer program but more than 60 different articles on widely different subjects outlining its method, scope, and verification. Extensive interlinks among the various articles and evidence are provided. No known existing health or other journal provides a logical format for publication of this type of a project. Only the Internet now appears to provide for an appropriate publication platform. And the concept of Global Engineering Analysis appears largely new to the health field. It is hoped that reviewers will understand this publication problem and view the result as a scientifically based project that has very important implications to our public health - and provide that 'peer' review that will be helpful to its eventual best acceptance.
The Doctor Should be Involved: Most actions advised in Life Ahead are via diet and exercise or other factors that must be managed by individuals themselves. But this or any other program of health maintenance should be done with periodic review and help from the doctor. Many health problems as for example diabetes can involve need for specialized diets that are not now considered a role of Life Ahead. Diets best for the health of most can have negative effects for a few. Many today need a doctor's exam and acceptance before starting even moderately intensive exercise. The doctor can help importantly if blood pressure or cholesterol is too high. Regular physical exams must be a part of responsible health management. Women have a particular need for regular female examinations. And the presence of various medical problems that are not a part of Life Ahead can alter an individuals proper approach to diet and exercise. Life Ahead shows that risks of disease can be drastically reduced by health actions. But no combination of health actions or lowest level of average risk can assure that an early major disease or death will not be suffered by some unfortunate persons.
Please browse some of the accompanying discussions. What Life Ahead Computes describes the program results in a bit more detail. More Well Days from Life Ahead tells how you can obtain specific added health benefits from things you can do. More Healthful Diets from Life Ahead tells you how to identify the health benefits of any specific food, combination of foods or diet. Losing Weight with Life Ahead suggests a new and quite different weight reduction program for trial.
