Hi Gretchen. I’m with you! This is a really satisfying part of my practice. One thing that I like to do with my seniors, and that they too seem to love, are reaction drills. Yep, go old exercises to test and improve their reactions, quickness and hand-eye coordination. At first, as you can imagine, these drills/exercises can be a bit frustrating for them, so I’m careful in keeping it simple and things that they can achieve with a little bit of concentration and effort. Then as they begin to improve and I start to increase the intensity, you can just see them light up and rise to the challenge. I love it!
