| If books had never been discovered, man
would have found some other way of recording his communication. But then, for
our consideration, we should include as books everything that is a written
record. This would include tablets, papyrus and anything else—including computer
diskettes. In the case of music, it would be impossible to think that man can

However, a group of researchers at John Moores University has just come up with a medically useful answer. It is that while 70-year-old men have the hearts of 70-year-olds, those of their female peers resemble the hearts of 20-year-olds.
David Goldspink and his colleagues looked at 250 volunteers aged between 18 and 80 over two years. All the volunteers were healthy but physically inactive. The team’’s principal finding was that the power of the male heart falls by 20-25% between the ages of 18 and 70, while that of the female heart remains undiminished.
