Heart palpitations are described as feeling like your heart is racing or pounding. Palpitations can be caused by anxiety, panic disorders, overeating, pregnancy, and abnormal heart rhythms (arrhythmias). Most palpitations are not serious, however, palpitations caused by a heart condition like atrial fibrillation or Afib can be serious and require medical treatment.
WEIGHING BY DIFFERENCE (From Dr. David Chesney) Weighing by difference is the most accurate method to measure quantitatively the mass of a solid sample. This procedure involves repetitive weighings of a weighing bottle containing a quantity of solid reagent. As the solid is removed to another vessel, the mass of the weighing bottle contents decreases.

It just does not make sense because one pound is one pound.
