Today become Actor

Today i become actor. I act as a blind man walking down the staircase and knocked by a group of students. Only one student is willing to help the blind man walk down the stairs. The shooting started at 11am ended at 3pm. Quite alot of shooting retake. Lunch skipped and in the end only having tea break at 330pm. Around 5pm, started to headache, this is the symptom of irregular meal time. I cannot skip meal if not i will headache and feel uneasy.
