Extreem changes in a system deeply adapted to a current situation is always a problem, that's why you hear mostly about the down and not the up. Slow or local changes are ok because life adapts nicely. Brutal or global changes will also see adaptation, but will cause much pain and damages. Moving a cristal glass on a few yards or meters at the average speed of 4 miles or km an hour may be fine for the glass or not, depending if your speed is mostly constant, or not. If you move the glass excrucingly slowly first, of throw it brutally at the last inch/cm, it will be bad for the glass. You won't hear about the good stories about this, because there are not aligned with the nature if the situation.
