つい先週までは「秋深し」という感じでしたが、今朝は出かけるときにすれ違う中学生の息が白くなっているのに気がつきました
でも何故か私の息はほとんど白く見えません
はて?
ここから先は想像ですが、私は歩き始めて1分程度ですが、彼らの目的地の中学校はあと100mほどです。
つまり彼らは運動によって体温が上がり、呼気の温度が高くなっているため、大気温度との差が大きくて白く見えやすいのですが、私は歩き始めたばかりでまだ呼気の温度が上がっていないせいではなかろうか?
それとも歳のせいで若者よりも体温が低い?などと考えましたが、約10分歩いて駅の近くまできた時には、私の息も白く見えたのでちょっと安心しました
Until last week, I had been felt it was deep autumn.
However this morning I realized that the breathings of the junior high school students walking toward me were making the white vapor.
But my breathing didn’t make it. Why?
This is my guess that I just started to walk and the school of their destination was only another 100m.
So their body temperature were coming up by their walk exercise and it made their breath white.
But my exercise was not enough to make the temperature increase.
Or I thought my temperature was lower than young people because of my age.
But about 10 minutes later when I reached to the station it seemed white too and I was little bit relieved about it.
