Ignore the misleading Youtube title – it should be “EPIC drumming WIN”. This guy is the embodiment of awesomeness. Trucking on despite losing his lunch. If pain is an indication that you are pushing yourself to your limit, then the puke here is weakness leaving the body. I suggest watching the full 2.5 minutes to allow the full experience of awesomeness to overwhelming you.
This scene reminds of me when I was teaching an Aikido kids class last year. A 6 year old had gotten out of the mat to throw up. What he did immediately afterward made him a god among elementary school children.
