Traveling is great, sometimes expensive of course and dangerous. Why is great because you meet and discover new traditions in new countries ,people and the way they used to live. Many wensites does the analyse of the best country to live or worst because of the enviromental reasons. I didn't see any raitings of the second semestry but I think like in a previous year it will be Canada , well I am not sure but the small chance is. If you not travel your brain and other systems get bored without any new information ( thats why some people read travel books in the metro, they imagine themselves in other conditions)
