Energy-conscious

Our bodies are made of matter and energy. The matter is mostly a mixture of oxygen, hydrogen, carbon, calcium, nitrogen and phosphorus. The energy comes from electrical impulses and chemical reactions, which then becomes kinetic energy when we use our muscles.

According to the laws of thermodynamics, after the universe was formed there’s no more and no less energy to be had. Instead, energy continually gets transferred from one place to another and transformed from one thing to another.

As individual human beings we have a choice in how much energy we consume - through the type and amount of food - and how much we expel – through thinking, feeling and actions.

Would it be useful for our wellbeing to work out: (i) If we’re satisfied with the everyday ebb and flow of our energy levels? (ii) If we’re putting the energy that we generate to good use?
