This is just my diary, there is no special information of chess
When I was 18 I began Shorinji Kempo as university club which is similar to Karate.
After the graduation of univ. I'd been far away from it.
Well recently I began another art, iai(battojutsu), which focuses on how to handle a Japanese sword.
However this is made of metal and still dangerous if it is mishandled.
