Things drummers do all day, everyday. These are the most crucial aspects of a drummers life. If they're not eating, they're sleeping and if they're not doing either of these things then you can guarantee they'll be drumming. Hell they might even be mixing it up. Drumming at the dinner table with bread sticks, cutlery, salt and pepper shakers, anything they can get their hands on!
Simple and to the point. What life is all about.
