9. The Number of Bones
You might be aware of the fact that an adult has 206 bones in the body but do you know that a baby has 350 bones? Probably no, but this is a fact that as babies, we start off with 350 bones in the body. However, as we keep growing, the bones fuse together and so the number is reduced from 350 to 206. This denotes that a lot of bones are fused during the growth years.
