Life expectancy would grow by leaps and bounds if green vegetables smelled as good as bacon. 
Hello Elfun i have come to bring great joy to you. Such wonderful revelations for one such as yourself:
By observation of the natural tendency of the organs of sense-the guidelines of determing what is nutritious-by whih all animals are directed to their food, we find that when the carnivorous animal finds prey, he becomes so much delighted that his eyes begin to sparkle.
He boldly seizes the prey and greedily laps the jetting blood. On the contrary, the herbivorous animal refuses even his natural food, leaving it untouched if it is sprinkled with a little blood. His senses of smell and sight lead him to select grasses and other herbs for his food, which he tastes with delight. Similarly with the frugivorous animals, we find that their senses always lead them to fruits of the trees and field.
In men of all races we find that their senses of smell, sound, and sight never lead them to slaughtered animals; on the contrary they cannot bear even the sight of such killings. Slaughterhouses are always recommended to be removed far from towns; men often pass strict ordinances forbidding the uncovered transportation of flesh meats. Can flesh then be considered the natural food of man, when both his eyes and his nose are so much against it, unless deceived by flavors of spices, salt, and sugar? On the contrary how delightful to find the fragrance of fruits, the very sight of which make the mouth water! It may be also noticed that various grains and and roots possess an agreeable oder and taste, though faint, even when unprepared. Thus again we are led to infer from these observations that the natural food of man was intended to be a frugivorous animal.
What is natural living? Livng depends on the selection of (1) FOOD, (2) DWELLING, and (3) COMPANY. To live naturally the lower animals can select these for themselves by the help of their instincts and the natural sentinels placed at the sensory entrances-the organs of sight, hearing, touch, smell and taste. With men in general, however these organs are so much perverted by unnatural living from infancy that little reliance can be placed on their judgements.To understand, therefore, what our natural needs are, we ought to depend on observation, experiment, and reason.
