10 minutes smiling, 10 minutes listening

‘Self sports’ is a video series about time, action and change. I do one action such as smiling, listening without stopping during 10 minutes. As time passes by, even though I am smiling, it doesn’t look like smiling and it becomes some kind of weird look. Because I try to not to move as much as possible, my face muscles begin to stiffen and sometimes get a tic without my intention. 10 minutes listening is listening to a cactus pot. I put my hands beside my ears and pose listening something very carefully, but I cannot hear any sound from the cactus and even the video has no sound.
