The death of a cell.
This picture is an amazing 3D illustration of apoptosis. The word “apoptosis” originates from Ancient Greek ἀπό, “away from” and πτῶσις, “falling” and it is a regulated process of cell death. 
There are two ways of cell death: necrosis and apoptosis. Necrosis is a form of traumatic cell death that results from acute cellular injury, and it usually causes inflammation, because of cell’s content released outside in the extracellular fluid. Apoptosis, on the other hand, could confer advantages during an organism’s lifecycle and it produces cell fragments called apoptotic bodies that phagocytic cells are able to engulf and quickly remove, before the cell’s content spills out onto surrounding cells, causing damage.
A cell initiates intracellular apoptotic signaling in response to a stress, which may bring about cell suicide. The binding of nuclear receptors by glucocorticoids, heat, radiation, nutrient deprivation, viral infection, hypoxia and increased intracellular calcium concentration, for example, by damage to the membrane, can all trigger the release of intracellular apoptotic signals by a damaged cell. 
Research in and around apoptosis has increased substantially since the early 1990s. In addition to its importance as a biological phenomenon, defective apoptotic processes have been implicated in an extensive variety of diseases. Excessive apoptosis causes atrophy, whereas an insufficient amount results in uncontrolled cell proliferation, such as cancer.

We really have to understand the person we want to love. If our love is only a will to possess, it is not love. If we only think of ourselves, if we know only our own needs and ignore the needs of the other person, we cannot love. We must look deeply in order to see and understand the needs, aspirations, and suffering of the person we love. This is the ground of real love. You cannot resist loving another person when you really understand him or her.

From time to time, sit close to the one you love, hold his or her hand, and ask, ‘Darling, do I understand you enough? Or am I making you suffer? Please tell me so that I can learn to love you properly. I don’t want to make you suffer, and if I do so because of my ignorance, please tell me so that I can love you better, so that you can be happy.” If you say this in a voice that communicates your real openness to understand, the other person may cry.

That is a good sign, because it means the door of understanding is opening and everything will be possible again.

Maybe a father does not have time or is not brave enough to ask his son such a question. Then the love between them will not be as full as it could be. We need courage to ask these questions, but if we don’t ask, the more we love, the more we may destroy the people we are trying to love. True love needs understanding. With understanding, the one we love will certainly flower.
