In a normal lat. CXR, we cannot visualize the spine clearly at the shoulder region due to all the bones and dense tissue. But as we descend down to the lumbar region, it appears darker (and clearer). This is called sometimes "the more-black sign." And it indicates a normal spine and posterior lung regions.

In a lower lobe pneumonia, especially in the posterior region, the consolidation affects the visualization of the spine. So instead of appearing darker and clearer as we go down, it gets more obscure. This is called "the spine sign."

شوفوا ناس حلوة قبل لا تموتون

قال الإمام زين العابدين لرجلٍ من جلسائه: إِتَّقِ الله وأجمِلْ في الطَّلَب، ولا تَطلُب ما لم يُخلَق. فقالَ الرَّجلُ: وكيف يُطلَبُ ما لم يُخلَق؟ فقال: مَن طَلَبَ الغنى والأموال والسِّعة في الدنيا فإنّما يَطلُبُ ذلك للِراحة، والراحة لم تُخلَق في الدنيا ولا لأهل الدُنيا.

The principle here is that once our physical needs are met, the major reward we often seek is social status, which by its very nature involves a comparison of us to other people. Money, titles, even awards of some sort become important mainly to the extent that they constitute and reflect social status, especially for those already wealthy, i.e., those with the most power in our society.
