Enhancement not only allows the possibilities of a healthy fullness and exuberance, but of a rather ominous extravagance, aberration, monstrosity ... This danger is built into the very nature of growth and life. Growth can become over-growth, life 'hyper-life' ... The paradox of an illness which can present as wellness - as a wonderful feeling of health and well-being, and only later reveal its malignant potentials - is one of the chimaeras, tricks and ironies of nature.
Oliver SacksIn examining disease, we gain wisdom about anatomy and physiology and biology. In examining the person with disease, we gain wisdom about life.
