Bananas are radioactive.

They contain a small amount of potassium-40, a naturally occurring radioactive element.

Fortunately, scientists have developed the Banana Equivalent Dose (BED) to help put this into perspective. Essentially, if something carries the same risk as eating a banana, it’s hardly worth worrying about. So, you can enjoy your fruit without any fear of glowing in the dark.

The BED is actually a useful way to think about risks in life. If something feels as low-risk as eating a banana – familiar, harmless, and certainly not life-changing – it’s probably fine. But just because a risk seems small doesn’t always mean it’s worth taking. Sometimes, choosing the safer route is not just sensible, but the wisest course of action.

Consider crossing a road. You could wait patiently for the light to turn green, or you could dash across between the cars, relying on quick reflexes and a bit of luck. Yes, you might make it, but why gamble when the safer option is right in front of you? Both choices get you to the other side, but only one guarantees you’ll arrive without a close encounter with a heavy object.

Now, think about baking a cake. You could follow the recipe exactly -measuring the ingredients precisely, preheating the oven, and mixing everything just right. Alternatively, you could estimate the quantities, and hope for the best. Occasionally, that might work. But more often, you’ll end up with a brick rather than a cake. Following the recipe, much like taking the safer route in life, generally leads to much better outcomes – especially if the goal is a cake you can actually eat.

Then there’s my measure, the Marshmallow Equivalent Dose (MED). Imagine making a minor social mistake like mispronouncing someone’s name or sending an email to the wrong person by mistake. The impact? Minimal – perhaps a little embarrassing, but hardly catastrophic. It’s about as bad as accidentally sitting on a marshmallow – soft, slightly sticky, but not life-changing. However, when the stakes are much higher – such as deciding whether to invest your savings in a risky venture – it’s usually better to pause, consider the risks, and think carefully before acting.

Ultimately, life isn’t always about charging into the most daring, risk-filled decisions. Sometimes, the smart choice is the safer one, where the worst that could happen is a minor stumble, like tripping over a marshmallow. Success doesn’t require reckless decision-making. More often than not, it’s about making thoughtful, well-considered choices.

Then again, you could spend your whole life avoiding puddles and still get caught in a downpour. Playing it safe might keep you dry, but sometimes the best stories come from dancing in the rain.
