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.
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
