Shopping list.

Imagine writing a grocery list by hand, not with a ballpoint pen, but with the deep red ink of your own blood. It sounds like something straight out of a horror film or a gruesome gothic fantasy, but in fact, there are people who mark off their most mundane tasks with this dramatic gesture. While it may seem macabre—or downright terrifying—there are actually a surprising number of reasons why writing your grocery list in blood might not be such a bad idea.

Of course, the image of someone poking themselves in the kitchen, carefully collecting their blood and then elegantly writing “bread, milk, eggs” on a piece of paper is a repulsive one for most. But if we look past the initial shock, there’s an underlying logic that can be both practical and personal. It’s all about the intensity and deep symbolism of the gesture, transforming the mundane into the memorable. Let’s take a closer look at four striking reasons why this grim idea might actually be a brilliant one.

1. Lasting Reminder of the Indispensable

How often do we forget an item on our grocery list, even when it’s literally right in front of us? A quickly scribbled note can easily go unnoticed among the many scraps of paper we encounter every day. A list in blood, however, sticks in your mind. Your brain responds to the dramatic and visceral image that blood conjures up. This makes it impossible to forget that you had to buy milk, because that list is deeply etched in your memory.

2. Eco-friendly Ink

In an age where we are becoming increasingly aware of our ecological footprint, writing a grocery list in blood can be seen as a surprisingly eco-friendly choice. Ink pens, especially the disposable ones, contribute to plastic pollution, and ink itself often contains chemicals. Blood, on the other hand, is a completely natural, biodegradable substance. By using your own blood as ink, you are contributing to a cleaner environment in your own grim way.

3. A Personal Touch

In a world where everything is increasingly digitalized and distant, writing a blood list is a personal gesture that is unmistakably “you.” It offers a unique, personal touch that nothing else can match. Every drop of blood on the paper carries your unique DNA, and there is nothing more symbolic than using your own life fluid to record your daily tasks. The grocery list is no longer a simple piece of paper, but a piece of you.

4. A List You'll Never Forget

Scientific studies show that people remember visual and emotional cues better than regular information. Blood evokes both visual and emotional responses. The image of your own blood, carefully used to write down an everyday task, will be forever etched in your memory. Every time you look at that list, you are reminded that this is no ordinary message; it is one that was carefully (and painfully) recorded.

Closing thoughts

While the idea of a blood grocery list may seem morbid or extreme, there are some surprising benefits to it. It ensures you don’t forget items, it’s environmentally friendly, and it adds an unprecedented level of personality to something as mundane as a daily task. Sure, it does require a certain amount of guts and a steady hand. And, let’s face it, it’s probably best to keep it a one-time thing. After all, no one wants to open their wrists to get a carton of milk every day. But the one time you do? You’ll never forget it.
