What is the oldest and youngest member to achieve a Black Belt?

There have been several Universal Self-Defence Black Belts tests achieved by both male and female members as young as 9 years old and up to 55 years of age. Whilst black belts tests for under 10 year olds and over 50's are a little rare it is obviously achievable and with the introduction of our new Cubs class and improved training methods I expect more barriers to be broken.
