stronger after age 30

Explanation:

Bones in different parts of the body (legs, arms, spine, pelvis) have different growth - related characteristics. They grow at different rates throughout development due to various factors such as hormonal influences and mechanical stress. Growth doesn't stop at a fixed age like 18 for all these bones uniformly, and bones don't generally get stronger after age 30 in a simple sense as bone density starts to decline in many cases after peak bone mass is reached around age 30.
