Dissipation is a predisposing cause of consumption. In this way consumption is the wages of sin. Dissipation is a scattering of vital forces by excessive indulgence of any kind. It always strikes at the most vulnerable point, and this is true when the indulgence even seems to feed the body. Whatever makes for lowered vitality makes for consumption, and dissipation of every kind makes for lowered vitality. Dissipation which directly or indirectly grows out of the affinities of the sexes, self-abuse, sowing of wild oats, beau catching and all the arts and devices which go with it in these times, may make soil for tuberculosis by exhausting the nervous system. Loss of sleep, excessive eating and drinking, excessive use of tea, coffee and tobacco all are predisposing causes.
