Read these paragraphs that summarise the points against using computers.
I'm against using computers for a number of reasons. First of all, I think that
people often become dependent on computers and couldn't exist without them.
Secondly, I think computer users often become more isolated from others, because
they spend all their time in front of a monitor and never talk to people directly.
Furthermore, computers are addictive and users often spend all their spare
time playing games or surfing the Internet. And finally, there are the physical
dangers of using computers. For example, looking at a monitor for hours is very
bad for your eyes. Also, they say that the electromagnetic rays which come from
monitors are very bad for you.
