In the first report I have compared the elements in soil and drink water of 14 so called long life and 7 short life villages.
This time I have analysed those of 10 long life and 12 short life villages (Table 1, 2). By their milligram equivalent ratio, I could described most clearly the difference between both villages, that is the ratio of Mg/Ca, Ca/K, Ca/Ca+Mg+K+Na, Ca-Na (Fig. 1, 3). Over again by the distributions curve of those equivalent ratio, it shows more evidently the difference both villages, such as the ratio of Mg/Ca on the lengthwise the ratio of Ca-Na on the breadthwise (Fig. 4, 5, 6).
Farther I have analysed the trace elements in soil, such as Co, Cr, Cu, Ni, Cd, and that of short life villages content always 2-3 times more than that of long life villages (Table 3).
