Everything you need to know

What: Yes, we know it sounds scary, but actually, this is something rather soothing, once you get your head around it. The point is to tidy your life, as if you were about to leave it. Just as you wouldn’t go on holiday without emptying the fridge, you need to audit your life, clean it, and tie up loose ends. Basically, put your life in order so your loved ones don’t have to.

Why: We all have more stuff than we used to, much more. We have cupboards full of clothes and shoes; freezers full of ready meals; sheds full of irresistible Lidl offers; not to mention online subscriptions and digital footprints. Often, we don’t have the stuff we need — wills, vital medical information, directions around care in the event of an emergency. Our relatives are left to sort it all out if we die or become incapacitated. We need to spare them this.

Why Now: Because this taps perfectly into the trend for simplifying and stripping back our lives; and also into the trend for mindfulness. Because the sense of satisfaction will be huge, and because we need to be clear about what should happen to our Facebook account when we’re gone. How:

De-clutter with serious intent: Do you need it? No. Then chuck it. Sort through your paperwork; no one needs 10-year-old gas bills. Put your important stuff — financial, legal — in an obvious place, and make sure it’s up-to-date.

Who: The Swedes, presumably. Anyone with secrets they don’t want discovered, or anyone paranoid enough to care about what happens to their personal information after their death. Fans of Marie Kondo, who are looking to take it to the next level.
