Pros
Learning about a new culture, history, people´s ways, including the fairy tales around the lovely Irish Celtic people. Having the possibility to gain good money and save money because all expenses are covered. When the experience goes well you create new bonds, new friends, new families. Improving the English language. Having a retirement plan.
Cons
It´s kind of a sacrifice in a way when one takes this leap of faith, leaving behind everything that one knows and not disconnecting properly at the end of the working day because you are living in. It takes a toll somehow, like the life of any emmigrant. One more reason to take all opportunities to take care of oneself with outdoors activities, connecting with people, visiting museeums, libraries, gym, walks or anything one likes to do on its regular life transforming the cons into pros.
