I wonder how they figured out the LD50 of water? Did they force water into 100 humans until half of them died?

Haha ~ interesting question
It didn't specified clearly in the video, but most of the time, people use rat as a model.
From wikipedia, it was 90 ml/kg in rats, which is similar to the value reported in the video, so I would guess it is a value from mouse model and translate it to human.

Make sense, but those poor mice :0

That might have been done during WW2...

嗯... 中學體育堂老師有提醒過,跑圈後不要一次灌很多水xD

哈哈~
真的嗎?我們只有叫不要立即坐下!其實我到現在都不太明白這個

可能是血壓問題?我都有聽過。可能同冬天浸溫泉不要突然站起來之類一樣xDD
