This is pretty ridiculous advice.

Death has a 100% chance of happening to all of us, and it is rarely predictable.

Being healthy and safe won't save you from a drunk driver, for example.

Seriously, not having your own burial arrangements, design headstone and plot already paid/picked out is nearly as bad as people whom selfishly commit suicide, get into drugs and/or make their lives trainwrecks and shift the costs, burden and agony onto the living. In the mortuary industry, it's called "pre-need" and it's way cheaper (adjusted for inflation) to get it done in today's money than decades later. Plus, there's pre-need cremation for those whom don't want to go in the ground in a vault+casket, which also cheaper.

I would worry less about drink drivers.

Live your life is my advise.

Reality is after handing over the site it'll possibly die anyway.
