characteristics. These characteristics include:
1) reproduction
2) growth
3) metabolism
4) movement
5) responsiveness
6) adaptation
Not every organism exhibits all these features
and even nonliving things may show some of them.
However, these characteristics as a group outline the
basic nature of living things.
The human life force seems at first sight to be purely
a matter of biology.
But the sequence of birth, childhood, maturity, old
age, and death is also a social one, for its length,
stages, challenges, and opportunities depend very much
on the society in which one lives.
How long we live for example is
strongly influenced by social as well as biological factors.
In modern industrialised societies we associate the idea
of death with the aged, but in traditional pre-industrialised
societies more people died in childhood than in old age.
Thanks to such social factors as modern medicine, improved
nutrition, and higher standards of sanitation, infectious
diseases such as smallpox, diphtheria and cholera no
longer kill more than half of all children before the age
of ten.
Every society imposes its own conceptions of a life course upon
the physical process of growing up and growing old.
Consequently the period from birth to death is arbitrarily
sliced up into a series of stages. Each offering distinctive
rights and responsibilities to the relevant age group.
The number, length, and content of these stages vary from
one society to another. But each society must socialise
its members into accepting and effectively performing
their changing roles of each stage in the sequence from early
childhood until death.
