Why does the writer suggest that you should do the work yourself?. [br] [origin

The lights have fused, the cooker is not working properly and you have just had an electric shock. You may need an electrician. But before you decide to have the house rewired, stop for a moment and think how much you could save by doing the work yourself. Not knowing how to do it is no longer an excuse when there are a hundred and one books, magazines and manuals on the subject. Not is it difficult to find the right tools and materials nowadays, with at least one D.I.Y. shop in every town.
     The do-it -yourself shop is a curious establishment. In it you can find anything from the tiniest screw to a self-assembly greenhouse. There is paint, glue, oil and wire for all purposes. There are tiles, selves, carpets and pipes of all shapes and sizes. You can even buy a complete bathroom suite in the larger self-service stores.
     Today there is much more leisure time and, in many cases, much less money available. Do-it-yourself has become a money-saving hobby. It is no wonder that fewer tradesmen make a living from private homes. Pipes can be joined together by pushing, paint that can be rolled on doesn’t drip, and holes can be drilled at the press of a button. Anyone can do it! Well, almost!
