Hi,
thanks for your replies. In relation to older urine,when I said vintage, I meant more like 7 years old ,rather than a few days. I have fridged urine and drank it several days after new,with no ill effects.The old(not fridge-cooled) is turning a nice deep brown after mid-December pouring. That is my future burns-aid ,if and when. I don't understand your word messy for it. My 'vintage to be' smells more,but is just liquid, not thicker,sticky ,or anything similar.So according to you, now I have murdered several parasites. Can't be bad ! :) cheers, riv.
