For most people, old age is feared because it is associated with disability and disease, and it is true that the prevalence of disease increases decade by decade. However, the ageing process is not the principal cause of disabling disease, and many of the disabling diseases of old age are preventable.
It is true that disease occurs more commonly as we grow older. With every year that passes the probability that a person will develop or be diagnosed as having a disease increases but this does not prove that ageing causes disease. The reason for this increase is the ridiculously simple explanation is that every year that passes means that the person has been exposed for yet another year to the risk factors that cause disease. It is usually the length of exposure to risk, both environmental risk and lifestyle risk, that causes the increase in disease not the ageing process.
The Actual Rate of Decline is faster than the Best Possible Rate of Decline, that is the rate of decline due solely to the ageing process and the difference between the two is the Fitness Gap. Both the point at which physical decline starts, and the rate at which it proceeds is for the first few decades determined by loss of fitness, and loss of fitness is determined by social factors, namely by the decisions people make about their life and the pressures which influence them decreases
Fitness has four aspects, all beginning with the letter S, and what we call the fifth S, namely the pSychological benefits of exercise
There are only two phases of life, the phase of growth and development and the phase of ageing and functional decline which is at present untreatable but there is great interest, and considerable investment, in the search for what would have been called an Elixir of Life but is now called Regenerative Medicine
It is important to appreciate just how serious people are about this mission. The key term is Regenerative Medicine and particularly in the USA where big powerful research centres, like the SENS Research Foundation in Mountain View, California, based on their belief that ‘ a world free of age-related disease is possible’ and new companies. The Financial Times (FT) on its front page on the 5th of September 2014 that Arthur Levinson, who developed Genentech, the company that was the first to use the knowledge locked in the human genome to create new drugs, had resigned from the board of Roche, which had bought Genentech. The reason was to devote himself to this mission. The ‘ 64 year old’, as the FT pointed out, who is also chairman of Apple, will head the mission started by Google, also based in Mountain View to extend healthy life. The new company he will lead is called Calico, short for California Life Company, not only has the firepower of Google behind it but will also benefit from a huge investment from another drug giant called Abbvie
The Ageing Process is normal, biological and not pathological, and nothing can be done about it, for the present at least. But this does not mean that you should despair. On the contrary, you need to understand what is happening to you and how the three processes that cause much more trouble than ageing, at least before the age of ninety can be countered, how their impact can be reduced and how many of their effects can be reversed – the three processes are
- loss of fitness, both physical and mental
- preventable disease
- a negative and pessimistic attitude
The Amazon Single titled An Antidote To Ageing summarises and explains the science and research that supports the proposal that instead of worrying about ageing you should take action to prevent, mitigate and reverse the three factors that cause many of the problems hitherto always ascribed to ‘ageing’.
There is increasingly strong evidence that many of the problems that have been blamed on ageing are in fact caused by either social or environmental factors, with their influence felt from the earliest age. Furthermore it is now clear that much of the research that has been done on old age has had serious flaws which have over emphasised the effects of ageing. Simply comparing people who are eighty with people who are twenty is not a fair comparison. When a different research method is used which follows people from twenty to eighty, a method called the ‘life course method’, the reduction in muscle strength that occurs is much less than when the muscle strength of today’s twenty year olds and today’s eighty year olds are compared directly, and the same applies to many other changes. If you want to know more consult the excellent book A Life Course Approach to Healthy Ageing by Diana Kuh and colleagues.
A linked site on Good Health in Your Seventies gives practical advice to people aged seventy and older on the steps they can take to feel better and prevent and postpone many of the problems that are currently assumed to be due to the ageing process.
