"because they skipped puberty."

Because breasts are made of fat similar to asses

therefore, long distance female runners who are made of lean muscle and are burning off enormous amounts of calories do not have fatty tissue in their asses or breasts and why they are built differently than the more muscular female sprinters.

better questions, why do fat girls have big breasts.... because they're fat.

Why do skinny girls have big breasts... because they're fake.
