Unit 14-M3

What mechanisms have been put in place to prevent or control the implications described for P6?

For P6 the problems were back ache, head ache and all of that.
So the methods to prevent all those problems could be measuring the chair so you can sit right and so that you are comftable where you sit and how you sit. Health and safety issues sorted, so that you are happy and you are not getting aches. Also other health and safety issues making sure the computer is in the right position for you to see so it is clear and you can understand it probably. 
Also- Spending too much time on the computer can also affect your social life.  Many people spend less time actually taking to their friends and more time texting and on social networking sites.
