How Tall Would Humans Be If They Kept Growing As Fast as a Baby

In the latest installment of what if?, xkcd takes on the hypothetical question “what height would humans reach if we kept growing through our whole development period at the same pace as we do during our first month?” According to xkcd’s calculations, a 7-year-old would be 13 feet tall and a fully grown 20-year-old would exceed 30 feet in height.
