Teaching drums to adults is a mixed bag, as they have been using their body and mind in a more routine fixed way.  Children are less coordinated and capable of doing complex motor tasks, but they have greater access to the new and undiscovered.  Though adults are, contrary to popular belief, much better learners as they have more mind body connectivity and coordination.  From West London Drum Tutor, drum lessons in Harrow, London www.westlondon-drumtutor.com
