1 Measuring the length of long bones can give an estimate of age for children, but this technique is useful only until bones have stopped growing. 2  The tibia completes growth at about age 16 or 17 in girls, and 18 or 19 in boys.he ends (epiphyses) and bony shafts (diaphyses) of long bones form separately in the womb. At birth, the ends of the long bones are mainly cartilage, with centers of bone beginning to form inside.
By measuring telomeres, some scientists believe they can determine biological age, which doesn't always equal chronological age. That means some people may be biologically older or younger than their age, said Jerry Shay, professor and vice chairman of cell biology at UT Southwestern Medical Center in Dallas.
