Wow, that makes me feel really grateful to live in Europe. Health insurance isn't an issue while travelling within the EEA/Switzerland because we get it for free through a cross-governmental scheme, so international travel isn't a big deal here. Although healthcare quality does vary depending on where you are on the continent. Going further afield would have a cost, but travel insurance is generally pretty cheap from my experience.

Not that it's relevant at the moment! We're not planning any travel beyond the island until at least next year.
