cave mysteries

At the caves we visited there were little squiggly stalactite formations called helictites. Before they received this scientific name they wer known as cave mysteries, because noone was (or indeed is now) really sure how they form - against the forces of gravity, in a bizarre range of shapes, defying logic. This must also apply to my loss this week of 0.2kg - a loss I tell you!! It must be very closely correlated to the number of steps and hills I climbed, because it CERTAINLY was not related to my food intake. But I shall take and run. It brings my total loss so far to a round 6.0kg (over 7 weeks).
