Seventy-six-year-old thomas tripped on a garden hose and broke his leg. his 17-year-old grandson, austin, fell while skateboarding and broke his leg. why is thomas's injury more of a concern than austin's injury?

Because you are an old man. An elderly person's cells have difficulty regenerating compared to an adolescent's cells, such as Austin.

Explanation:

According to research, the elderly have great difficulties in bone fracture regeneration. This is because the cells of the elderly are aged and have failed regeneration of fractures, making healing of a broken bone very slow and can cause various problems for the elderly. On the other hand, adolescent cells have a high regenerative capacity promoting rapid healing of a fractured bone. For this reason, we can say that Thomas's 76-year-old injury is more serious than his 17-year-old grandson's injury.
