Just as man in his infancy is absolutely helpless and totally dependent on others, similarly man in the last stage of life also becomes totally dependent on others. Weak and sick, with all his senses failing, he is not able ’ to do anything himself. Toothless like an infant, at this stage of life, he stands at the door of death.
