You know it's very difficult to be an actor, and to have people depending on you to say the right line, at the right time, and to not be able to hear your cues! I can't tell you how many times I would've had to have said What? if I didn't have my hearing aids. So my hearing aids are a life saver, and they allow me to practice my craft.
I'm afraid if I don't keep moving, they're going to catch me ... I am 81 years old and I want to see what's around the corner, and I don't see any reason in the world not to keep working. But I am starting to value my down time a great deal because I am realizing there might be other things to do that I am overlooking.
