Writing Feedback / machines are really useful if you get them rightly; but simple work by hand [4]

Hi all, I am a newbie from Vietnam and this essay as below I also write fristly. I am not sure that my essay go right completely and really need some comments form you to fix the mistakes :)

Topic :" Some people like doing work by hand. Others prefer using machines. Which do you prefer?"

My writing :

Nowadays, the development of science and technology have increased the quality of life. Appearing many kind of machines to attend to people. Some people prefer using them, but others like doing work by hand. To me, I prefer working by hand.

Fristly, working by hand that means I must have reponsibility for my products. Machine can produce fastly not only the quality but the quantity, unfortunately if something go wrong, the consequence would be so terrible.

Secondly, handiwork make me more happy and reduce the wastefulness. The daily works with machines would make you feel boring, even you could get much stress at your jobs. The effect of machine on people could give you something you do not want. More a problem is the your finance, you would save a large sum of money if you do not spend your money on buying machines that you can get more money to fix if they broken-down.

Another reason I support for working by hand is the health. Many people are independent on machine and their activities also reduce, their arms and legs are not useless and certainly the healthy would go down slowly. There are many invention for moving as motorbike, car, plane.. of course they are useful but the asmostphere is more and more pollted, while walking or bicycle can reduce the pollution. The health should set on the top of all, do not abuse so much at machine.

Ultimately, machines are really useful if you get them rightly and you should do by myself with some simple works what you can do. Any the abusing always go wrong and the health is important than all.
