Harvesting from the soil over time without adding to it ends with depleting fertility and leaving it without muscle or synapse.  Soil,   like the mind,  needs regular feeding to reproduce the fertility it was blessed with.
       Good compost may be likened,  in one's life, to the fully digested product of one's past material experience.  With water,  air, heat,  and those harvested materials from the past, a fungal,  bacterial enzymatic biomass is created  which will raise the composted materials into the fertile dust of renewal. The renewal takes time ;  heat, the right enzymes, destruction of pathological bacteria, aeration. watering, catalytic admixture, and earthworms who will tell you that you are on the right track.
       Is  mediation of the infertile mind the same  and as simple as the addition of the carefully prepared compost pile to the soil? Maybe not, but I have to give it a shot,  at least as hard as I work out at the compost bin. It seems to me that remediation of the mind is equivalent to the remediation of the dirt and equally useful.  Then you can trust that the ruminant harvests that you have brought up from your past will be re-digested with care  and  with  luck your muscle, muse, synapses, and mental fertility will be fulfilled and stimulate new growth in your life.  It's really just chewing the cud.
        We aren't that different from compost.  Both of us are special.  We both came from dirt and to dirt we shall return.

A farting horse will never tire : a farting man is the man to hire !
    My pioneer family's homely refrain was a reflection of the met nutritional needs of the working class , and the assurance that things were in working order at a time of deprivation.  A hearty meal for both horse and man, eaten quickly, provided jet fuel for hard work.  Possibly the more publicly flatulent , either horse or man were what the jingle writer considered both unrestrained and therefore more " gung ho" in capability. Such an advantage in a hired man should be considered.
       The volume  of intestinal gas is increased with a high carbohydrate diet as would be expected in pioneer days. Moreover the  "poor man's food " of Brassicaceae and beans would have further contributed to this gas.  There is, when investigated, a high correlation of intestinal gas and caloric intake.  Mean total volume of intestinal gas produced in a day in a healthy adult averages 705 ml. and this includes both bolus gas  (swallowed air),  and gas from colonic fermentation. Bolus gas would be increased considerably in the  trencherman.  The speed with which the trencherman " fueled up " on these foods increased the air swallowing,  somewhat therefore reduced the percentage of colonic fermentation gas,  and made the emissions more fragrant.
        The daily and nightly  rate of emission of flatus was variable but enhanced  by heavy ploughing  and digging, as the horse and man toiled in the soil in those pioneer days, Photos of of pioneer days often reveal a sturdy obesity in the hired man that bespeaks strength and serves as a base of reserve  when horse and man enter stages 6 and 7 which leave one atrophied.  *   Obesity sort of getting a head start in life's race. Low carbohydrate diets  associated with high fibre  meals reduce flatulence considerably but at the expense of energy;  not desirable in the case of a hired man.
           There was little or no mechanization in the farm on those days,  One couldn't work to advantage on the farm without the hired man and the horse,  both running on all cylinders. It's just no surprise the horse and man lived in their own quarters, apart from the rest.
