On the one hand, cheese is an excellent source of minerals like calcium and magnesium, vitamins A, B2 and B12, not to mention being a complete protein. On the other hand, cheese is also a significant source of saturated fat and sodium in our diets. To lower saturated fat intake, consuming reduced-fat cheese is sometimes recommended to lower cardiovascular disease risk.
Life pits the order and intricacy of biology against the ceaseless chaos of physics. The second law of thermodynamics, or the thermodynamic arrow of time, states that any natural system will always tend towards increasing disorder. Biological ageing is no different, making death inevitable. However, one of the least-addressed questions of ageing is the apparent paradox between the optimizing drive of evolution, and the inevitable deterioration of the body.
You can live without food for three weeks and without water for up to three days. But you can’t live without air for more than three short minutes.
