Belly Button Trivia

Today, I'd like to introduce a useless trivia.

Heights of humans' navels are different in men and women.

Man's navel is located at the top of his pelvis, while woman's navel is located at higher than the top of her pelvis.

That is to say, you can distinguish between men and women from the heights of their navel.

However, I don't know whether such an opportunity comes or not.

By the way, in human skins, the navel is a only part that don't sweat.

今日は、あまり役に立たない雑学を紹介します。

人間のへそは、男女で位置が異なります。

男性は骨盤の上端の位置、女性はそれよりも高い位置にあるそうです。

つまり、へそを見れば男女の区別をつけることができます。

しかし、この判別法を使う機会があるかどうかはわかりません。

ちなみに、へそは人間の皮膚の中で、唯一汗をかかない部分です。

  You can also say "a piece of useless trivia".

• Heights of humans' navels are different in men and women.
• The location of the human navel is different in men and women.

  When you say 'heights of humans' navels', it sounds like you're talking about the height of the navel itself, not where it is on the body.

• Man's navel is located at the top of his pelvis, while woman's navel is located at higher than the top of her pelvis.
• A woman's navel is located higher above the pelvis compared to a man's.

  This is an easy way to compare both men and women, you don't have to say it twice for both men and women.

• That is to say, you can distinguish between men and women from the heights of their navel.
• That is to say, you can distinguish between men and women from how high their navels are positioned.

  Again, 'heights of their navel' sounds like you're talking about how tall their navels are, not where they are.

• However, I don't know whether such an opportunity comes or not.
• However, I don't know how often such an opportunity will come.

• By the way, in human skins, the navel is a only part that don't sweat.
• By the way, the navel is the only part of the human body that doesn't sweat.

  Just say 'human body' instead of 'human skins'
