Evolution results in a wide range of striking features in animals – vibrant colours, massive horns, flamboyant tails, rapid movement, loud calls and so on. These characteristics usually have an important and continuing function in nutrition, finding a mate, propagating the species, or avoiding predators.

What are our prominent features? Most notable are an upright stance, excellent vision and a large complex brain. But do we use them to the full? We have the ability to walk fast and cover long distances, but spend more time sitting or driving a car. We can see long distances and understand the intricate details of our environment, but spend much of the day squinting at computer and phone screens. It is possible we have the most complex and clever brains in the Universe, but how often do we use them to think logically or creatively?

An overused, but still pertinent, saying is that: ‘If you don’t use it, you lose it’. As animals, we are neglecting the important features which make us human, and tending to become sedentary, visually impaired, unthinking zombies.
