Read this essay. Are any of your ideas in it? Do you
agree with the writer and their conclusion? Why/Why
not?
In the last 50 years or so, new technology has made
massive changes to the world. Mobile phones, computers
and the Internet have all made the world faster, and so
have cars and other types of transport. But not everybody
agrees on whether these changes have had a positive or
negative effect on our health.
Our health has certainly improved in some ways. Firstly,
medical science has improved, which means that doctors
are better of curing and preventing illnesses now than in
the past. What is more, new technology has made our lives
eo.sier, for example by making it less necessary to use
physical strength.
On the other hand, technology has possibly made our lives
too easy. For example, some people go everywhere by car
and so they never get any exercise. Furthermore, today's
der has changed greatly. Nowadays
, people eat a lot
of processed food whereas in the past they ate fresh,
natural ingredients. In addition, today's lifestyle is very
stressful because of work and faster communication. As a
result, the risk of heart problems is greater now.
All in all, I think that, despite the advantages that modem
technology has brought, today's world is unhealther than in
the past. However, it is up to us as individuals to be aware
of the dangers and to take measures to make sure our
own lives are as healthy as possible, by eating well and
getting sufficient exercise.
