Lesson 37-3 The process of ageing 衰老過程
We are so familiar with the fact that man ages, that people have for years assumed
that the process of losing vigour with time, of becoming more likely to die the older we
get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a
pair of shoes. They have also assumed that all animals, and probably other organisms
such as trees, or even the universe itself, must in the nature of things ‘wear out’. Most
animals we commonly observe do in fact age as we do, if given the chance to live long
enough; and mechanical systems like a wound watch, or the sun, do in fact run out of
energy in accordance with the second law of thermodynamics (whether the whole
universe does so is a moot point at present).
