Check out this fantastic, classic video, featuring the training regimen of 6-time All Japan Champion - Masahiro Miyazaki. At the end of the video, there's a short monologue from him, where he says:
'So, you saw my today. Did you find in useful? I'd be pleased if everyone watching can make their dreams come true, by setting goals, and working hard towards them. Kendo doesn't have an ending, and you can keep practicing no matter your age. I'd like it if you continued Kendo for the rest of your life. This is what Kendo is.'
