I agree Grz, this is why those who try to discredit a protocal that has positive effects for others are in a foolish persuit! Some of us do fine on a vegan diet while others have dizzy spells and cannot function,that does'nt discredit the vegan lifestyle! The smoking issue is also a good example of consensis driving despite the fact that many live there intire lives with no real adverse effects! In fact in the records books on longevity many of the centurians who have out lived their offspring where smokers! However the old dictum "follow the buck" always seems to ring true!
However even if there are such things as nanobacteria that build little huts out of calcium phosphate it does not discredit the positive effects that many have found using calcium hydroxide in the proper manner! My own improvements on my body are very pronounced ! I did not even have to use knee pads this last tile job I did and found my knees and knee joints quit pliable and soft and experience none of the pain I have had in the past! So all the test group studies in the world would not disprove its viabilty to me!
