9/10 Practicing Karuta

I practiced playing Karuta by myself today. I was practicing in a Japanese-style room without an air conditioner, so I got sweat so much. But I feel refreshed after sweating a lot.
Sweating a lot is the one of my way to be refreshed. I used to do hot yoga to get sweat a lot and now I realized that practicing Karuta gives me the same effect as hot yoga.
