I will give a brief overview of what I do, how it works and then ask for either 1 or up to 5 volunteers who have some type of physical discomfort. Depending upon the volunteer(s), I will either do the tapping on the volunteer or a group tapping while explaining and sharing the process with the audience. You just never know who will be willing to stick their necks out doing this, so I will play it by ear. I can use 1/2 or an hour.
