Does it involve moving house or country? What would be the options if you didn't like it?
Yes, moving country. If we did not like it, we can come back to where we are right now.
Moving will put my husband in the prime location for his field.
Four years because that's how long the contract is. And then if I want, I can pursue my passion (hopefully) which I have just discovered last year. If I don't, I can still use the experience to either continue working in the field, or transition to another subfield.
