P 63 ex 8

You shouldn't use a computer or a laptop for long periods. Because computers can be a real pain in the neck, back, wrist and eyes-with long-term use. You should keep computer equipment away from edges of desks, organise cords in a safe way and attaché heavy equipment to walls or floors. Such simple ideas can prevent injures.
Gadgets are quite expensive. When you are out and about you can protect yourself from danger. You should keep your valuables such as MP3 player out of sight and your handbag closed.
Artificial light and low-level light from computer and TV screens- can throw off our circadian , with negative effects from depression to mood disorders. You should light up your working place well and spend more time outside. The internet can pull people away from local connections, chance meetings in public places like cafes. It can create a sense of social isolation. People must have real social life.
