  1. You poor thing!!! I hope you heal quickly! Luckily, you’re young so your body repairs itself far faster than in older people. Your bones are alive, just like your skin. And just like when you cut your skin and it forms a scab, the cells in your bones (osteoblasts) will form a “scab” and start to heal over the broken part of your bone very quickly. It takes time for this “scab” (it’s really called a callus) to become strong though…it’s made out of soft collagen and then cartilage before it becomes real bone.
