YOUTH PROLONGED: OLD AGE POSTPONED
by Robert Weale (King's College London, UK)
What exactly is human ageing? Can it be slowed down?
These questions have puzzled scientists and laymen alike
for generations, and continue to do so today. The author
addresses these thought-provoking issues by challenging
pre-conceived notions of age-perception, age-acceptance
and inter-age relations. Pertinent matters of age-related
communication are dealt with, and the reader is treated to
a grand tour of the latest theories of ageing, age-related
biological changes and age-related diseases, such as
Alzheimer's Disease. Here, the author's expertise in agerelated
eye diseases truly comes into its own.
Weale's unique work not only underlines important
genetic and avoidable risk factors but gives ample
consideration to possible consequences stemming from
different early lifestyles. Readers will re-consider their
ideas of what it means to age, and gain a better
understanding of what can and cannot slow down the
process of ageing.
