A person's grieving experience may differ from others in expression, intensity, and length. One can hide grief or express grief openly to others. One may feel intense sorrow and loss during the grieving process, while others experience less intense feelings. The intensity of feelings may be influenced by one’s beliefs about death. Someone may also grieve for longer periods of time, while others overcome their grief in a shorter amount of time.

The dog salivates due to the idea that food is related to the sound of the bell.
By using the radioactive dating to compare the ages of the rocks in different layers is the best way to compare the ages of layers from the two different areas as there is a sect in a rock formation, the oldest rocks are in the bottom layer and the most newborn rocks are in the top layer. Geologists have produced a set of principles to compare the ages of rock layers. They apply these principles to organize the layers according to their corresponding ages.
