Here you see me for several minutes the stairs in my house hall up and down running, first slowly and then faster and faster. My fat wobbles and I am slow thus from the puff, so I must do a little break. My heartbeat is so loud which I hear it self and I would not like to keep this from you of course. I take the microphone and press it on my skin and you hear my quick pulse! Please use for best hearing the pulse a headset! This is the wmv-videoclip version in resolution 640 x 480.
