How far behind should you stay from another vehicle in traffic?   The universally accepted answer to this is: 2 seconds in normal driving conditions (good weather & dry roads) and 5 seconds in inclement weather (ie: snow and icy â¦roads).
A typical human rib cage consists of 24 ribs, the sternum (with xiphoid process), costal cartilages, and the 12 thoracic vertebrae. Together with the skin and associated fascia and muscles, the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck, thorax, upper abdomen, and back.
Humans have 24 ribs arranged in pairs. Starting from the top the first seven pairs of ribs are called the true ribs, the 8 th, 9 th and 10 th pair of ribs are called the false ribs, while the last two pairs are called the floating ribs.
