People can wear whatever they like, as long as it is clean and decent ( I ban micro-skirts and naked belly-buttons). 人们可以穿他们喜欢的任何东西,只要干净得体(我禁止他们穿超短裙和露脐装)。
Individuals of West African-origin have longer legs than European-origin athletes, which means their belly-buttons are three centimeters ( 1.18 inches) higher than whites. 从个体比较,西非运动员比欧洲运动员的腿长,他们肚脐的位置平均比白人高出三厘米。
In the pool, meanwhile, whites have the advantage because they have longer torsos, so their belly-buttons sit lower on the body. 相比之下,在游泳项目上,白人较长的躯干和位置较低的肚脐是有利条件。
