Thank you for taking part in this project. Please take the time to record your mouth using your smartphone or camera as you sit and think about your life. Start by thinking of the challenging and bad moments in your life for two minutes, then think about the good and joyful moments for another two minutes. It may be easier to use the front facing camera of your phone. Try to be still and have good lighting during this process. Please upload the video here and fill out the survey below to the best of your capability.
