Question

Quizplus · Accepted Answer

As individuals start to grow, they experience rapid growth during their childhood years, which slows down as they approach puberty. Once they cross puberty, their height growth slows down even further, and by their mid-20s, most people have stopped growing altogether. This is because the body's growth plates, responsible for increasing bone length during childhood and adolescence, ossify (harden into bone) with age, resulting in a decrease in marginal growth.
