In the recent world, an increasing number of travelers choose destinations harder to reach, for example the Saraha deserts or the Antarctic. There are obviously some key merits and demerits those voyagers get from the challenging travels, namely, they can get to know the environments the areas are facing first hand. In addition, they can obtain special satisfactions only the people who overcame hardships can enjoy.

I would like to discuss the advantages and drawbacks with some background reasons in this essay.
