You're born with 300 bones, but by the time you become an adult, you only have 206.
Why is it so?
Which are the bones that are being degenerated?
 
The most degenerated bone is back bone. It consist of many small bones that degenerated wd maturity. That is the reason tht an infant is very flexible and a matured child is rigid
 
Our spinal bones gets degenerated. Regular exercise should be maintained still even after adulthood though. This is in order to keep the bones healthy and prevent degeneration as we grow older.
 
Just for the knowledge it is the sacrum and coccyx bone of vertebral column that becomes fused as we grow. There are finally 26 bones in the vertebral column in a normal adult.
In an adult the humerus is a single bone, composed of a shaft (diaphysis) and two heads (epiphyses), all fused into a single bone. However, in a growing child the humerus is composed of three distinct, separate bones, the diaphysis and the two epiphyses.
The adult has a right and a left humerus (= 2 bones) whereas the child has two epiphyses and a diaphysis on the right side and two epiphyses and a diaphysis on the left side (=6 bones).
When the child stops growing, the epiphyses will fuse with the diaphysis and then that child will also have 2 bones rather
than six.
 
Osteoporosis is a disease in which bones become fragile and more likely to break. If not prevented or if left untreated, osteoporosis can progress painlessly until a bone breaks. These broken bones, or fractures, occur typically in the hip, spine, and wrist
