Difficulty in Distinguishing Ageing and Pathological Processes
Those wishing to probe more deeply into the whole phenomenon of CVD must take account of the theory that the biological functions that decline gradually with age (line a in Fig. 2) are essentially the same as those that decline more suddenly in disease (line b). For this reason, as Keele and Neil write (1982, p 528), “It is often difficult to say whether degenerative changes are physiological or pathological in nature, but predisposition to fatal infections, malignant disease and cardiovascular catastrophes account for the vast majority of deaths in old people.” (Emphasis added)
