I was somewhat sleepy this morning.
I came here once, but I couldn't feel studying at all.
So I left here and did other something.
But my sleepiness hadn't gone away.
In addition, the temperature gradually became higher.
And then, I suddenly remembered a stuff I had bought before.
It's an ice bag.
I took out it at once, and put some ice cubes in it, and tried putting it on my head.
FEEL GOOOOOD!
My sleepiness left for somewhere.
I recommend applying it on your feet.
