the advantages and disadvantages of travel

traveling broadens our range of knowledge. not only that we could learn so much about different cultures and practices but also we could use the oppurtunity to relax ourselves. it would also be a good chance to train ourselves. traveling requires us to communicate with people that might be so much different with what we are. there could be great language and cultural barriers. the food would also be a big challenge for us, since it's a basic need that we couldn't avoid. our ability to adapt the environment would be well tested everytime we travel.
on the other hand, traveling usually costs time and money. it would be much better to travel not only when we possess enough money and time but also health. traveling are often tiring. we should make sure that we're in the proper health condition. and as mentioned before, money is an important aspect. unexpectable things often happen, and it would be somewhat easier when we have money for the unexpected.

there are huge differences in the price and travelling time. The price of a train is often stable, and the price doesn’t change during the high season, but the price of a plane is very good to purchase. There is usually a cheaper price of plane during the low season and the earliest or latest flight. What’s more, you can save more time by travelling by plane than train. For example, if you want to go to Sydney from Brisbane, you only spend about one and half hours going there, but to go there by train means spending about fourteen hours. In addition, it is exciting to do anything that you want on the plane during the flight. You can choose to watch movies, play TV games or listen to music on the plane for free, or you can use your laptop and not be afraid of having no power, because the electric power is also supplied for free. However, you need take radio or game boy machine to have fun by yourself when you travel by train.
