Thomas Jefferson Quote
With your talents and industry, with science, and that steadfast honesty which eternally pursues right, regardless of consequences, you may promise yourself every thing-but health, without which there is no happiness. An attention to health then should take place of evey other object. The time necessary to secure this by active exercises, should be devoted to it in preference to every other pursuit.
