pigment QUOTES

1 " Then what is good? The obsessive interest in human affairs, plus a certain amount of compassion and moral conviction, that first made the experience of living something that must be translated into pigment or music or bodily movement or poetry or prose or anything that's dynamic and expressivee--that's what's good for you if you're at all serious in your aims. William Saroyan wrote a great play on this theme, that purity of heart is the one success worth having. " In the time of your life--live!" That time is short and it doesn't return again.

5 " We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex.....we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body.
