On travel it is possible to have a rest, and to relax. But in too time if you have any animal, it there is nobody to leave. Also if you go to other country during academic year, you won't be able to attend school, and to gain knowledge. Every day it would be necessary to remember friends. But still there is also a sea (ocean) where you can swim for a while. During rest it is possible to gain strength. Rest abroad, not such and bad business!
