The Age of Unreason

                                                                Charles Handy

     In his book The Age of Unreason Professor Handy describes the dramatic changes that are taking

place in our lives today and warns that we must adapt to these changes if we  want  to survive in the

future.      

     Handy believes that in the future less than 50% of the workforce will   be employed full-time by an

organization. These full-time employees will be the qualified     professionals, technicians, and managers

who are essential to an organization. Their working lives will be a lot more demanding than today, but in

return they will be well-paid and they will retire earlier. The rest of the workforce will Be self-employed

or will work part-time, providing organizations    with    the products and services they require on a

contract basis.  Handy  forecasts  a  big  increase in the number of working mothers in future and believes

there will be a large number of unemployed.      

     Handy gives us plenty of figures to worry about. He estimates that by the year 2040, one person in

five will retire, and one in ten will be over seventy-five years old. There will be one retiree to every three

people of working age, and even more than that in countries such as Germany and Switzerland, where

the proportion will be as much as one  to  two.  Retirees will remain healthy and active for longer than

they do today and many will live to be a hundred years old, a fact which leads Handy to suggest that the

term retirement will no longer be appropriate. He suggests the third age is a more appropriate

description, since it will be as important a part of our lives as the first age of learning and the second age

of working are for us today.

2. According to Protcssor Handy, the future workforce will ____.

A. adapt to the changes in retirement easily

D. work on a contract basis

3.  From the last paragraph, we learn that about 30 years from now, _____.  

A. the number of retirees will double in many countries

B. ageing will be a common and serious problem

C. 10% of the population will live to be 100 years old
