I don't even know if I have grandkids 'cos my kids cut off all contact with me yonks ago - even blocked my e-cards on their birthdays....
The premiums from the insurance agent in PI are very reasonable TBH. At 65 years old, I still have loads that I want to doSure, I don't want to spend 50% of my pension on insurance premiums for a policy that I might never claim on, or that might refuse to pay out. But unless I have a wad of $$$ to put aside (which I don't), I think it is rather selfish to have no medical cover at all and to hope that friends and GoFundMe etc will step in when they scrape me off the road...
