Where I live there are an increasing number of crowd funders every year for people who have an accident on holiday and have no insurance. I have always thought this was a minority of people willing to accept this risk but yesterday I spoke to a younger colleague (I am 51, she is 32) who said that no one she knows ever buys insurance and it is seen as a foolish waste of money to her and her friends.
She is off to Indonesia for a month in August with her children - with no insurance!
YABU: I would go abroad without insurance
YANBU I would only go abroad if I had insurance
