Famous quotes containing the words nervous system, nervous and/or system:
“A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.”
—Lawrence Kutner (20th century)
“It is a bore, I admit, to be past seventy, for you are left for execution, and are daily expecting the death-warrant; but ... it is not anything very capital we quit. We are, at the close of life, only hurried away from stomach-aches, pains in the joints, from sleepless nights and unamusing days, from weakness, ugliness, and nervous tremors; but we shall all meet again in another planet, cured of all our defects.”
—Sydney Smith (1771–1845)
“My advice to people today is as follows: If you take the game of life seriously, if you take your nervous system seriously, if you take your sense organs seriously, if you take the energy process seriously, you must turn on, tune in, and drop out.”
—Timothy Leary (b. 1920)
