Why Normally Poisson Ratio Can't Exceed 0.5?

Poisson's Ratio and its significance:

Poisson's ratio, named after Simeon Poisson, is the ratio of transverse strain to longitudinal strain. It measures the tendency how deformation of one dimension affects another. Suppose if we stretch rubber band the length of the rubber band increases but the thickness/width decreases. This effect of one dimension deformation on another dimension is showed by Poisson's ratio.

Angelina Post-Breakup Trauma and Her Resilience

Angelina never thought how the happily flowing days could turn this harsh. Nor had she thought how the flowers of happiness could turn into thorny miseries. Seeing those ecstasy turn into grief she cursed life and God. The passionate lover of God was changed into atheist. God is only a joke for her now. She tore all the pictures of Hindu Gods of her room. She threw away all those idols of Gods. Those idols which were made of metals were sold to street metal refineries. Her life was crying hard and she didn't have any hope of being happy.
