“Scientists at Oxford University have made a startling discovery: they’ve found a region of the brain that makes you wonder if you’ve done something wrong, and whether you’d have been well advised to do something better.”
The region of the brain that allows you to consider your decision making is called the lateral frontal pole and it’s only in humans. It’s about the size of “a large Brussels sprout” and doesn’t taste any better.
So, after Adam and Eve ate the forbidden fruit, this area of the brain got its first exercise. Now that we know where it is, perhaps we can start putting it to some more exercise.
