This is 30 seconds of footage, looped 4 times to make the minimum length of clip available -- 2 minutes long. I chose to release this tiny amount of footage because this is when I had bronchitis two years ago from very bad allergies and it is a VERY deep bronchitis cough.  One of the coughing fits recorded was in the dark so you can't see much but can hear it.  This clip is ONLY for deep coughing/bronchitis loving enthusiasts, please do not buy it if you aren't okay with the short nature of the clip.
