My dad, who's almost 70, has been told he's got angina.
He's a keen traveller and is due to fly abroad on a European holiday soon - but he's not intending to tell the holiday insurance company.
I'm concerned that if something happens while he's abroad, he won't be covered for medical treatment there - and me and the rest of the family will be left trying to sort it out.
The parent of a friend, who also had angina, died mid-air a few years ago, so it's making me more anxious.
I can understand how my dad's looking forward to the holiday and he's probably worried he won't be able to go if he tells the insurance company, but I think he's taking too big a risk.
AIBU and WWYD? I've tried to persuade him to tell the insurers, but he's refusing.
