Grub before Class
I hope that you did well on your test. I have a tricky stomach, meaning at some of the worst times (yes in class) i get the worst cases of gas.
I am one to want to have something on my stomach before i get on the mat, but nothing to heavy cuz it will surely come back to haunt me at the worst time.
Why can't someone at Bujin design a hakama to conceal or refreshen gas?
Take care and congratulations.....
