Hyh:
Ofcourse in Canada and the US, the health system is very different and insurance can be a problem for anyone with a pre-existing condition, making life incredibly expensive or impossible if you suddenly become too sick to work.
And despite what people think you can’t just hop on a plane back to Blighty and use the NHS. Access to the NHS for free is based on residency, not the fact you’re British or have a British passport. Yes they’ll treat you if its an emergency but they’ll also look at recouping the cost if it is one of the things not included in the list of stuff that is free for all regardless where you come from or they’ll not treat you until you’ve paid up front if its non-emergency.
