Background: Soft water has low calcium+MG.
Result: suffering disease, with low level of calcium in bodies
Cause: because of drinking soft water.
Correlation =/ causation.
Pre-think:
1) another cause leading to the same result;
2) evidences that can increase or decrease the correlation level (if they still suffer disease without drinking soft water);
3) possibilities of reverse causation - not applicable
A - irrelevant
B - indeed, this could fill the gap;
C - irrelevant
D - irrelevant
E - irrelevant
