Question

What will be the disadvantages if time traveling will become possible?

Answer 1

The advantages and disadvantages of travelling.

There are many ways of spending free time. One of them is travelling. Certainly, it has its pros and cons.
First advantage of travelling is visiting interesting places and meeting new people. It is connected with getting to know other cultures and traditions which is surely valuable. Secondly, it is usually said that journeys educate, so whilst travelling as well as exploration we can make our knowledge wider. Also we become more experienced and ready to cope with surrounding world if we learn something while being in journey. Furthermore, travelling is the best solution for those of us who suffer from boredom or want to get away from ?grey reality? and experience great adventure. Journeys give to people a little fun and also make dreams come true.
On the other hand, journeys has some crucial disadvantages. Firstly, costs of travelling are often quiet high for example travelling by plane, so naturally not everyone can afford. What is more, journeys especially foreign ones expose us to danger of disease or even death. Travelling can lead to fall ill and maybe then to expensive treatment or in case of fatal accident like for instance car and aerial one to death of many people. The next disadvantage is fatigue that occur while travelling. Most journeys last very long and it can make us feel tired.
To sum up, travelling is a very good way of spending time. It can educate, give impressions, nice memories and let make friends. However, in my opinion travelling in spite of its whole advantages, it should not be the only way to learn about the world.
