Young ===== Birth to 25.46 years
Middle Age = 25.46 to 50.94 years.
Old ======= 50.94 to 76.4 years


Questions?

Should we include childhood in this? Or are we looking at three ages of adulthood?

In which case young would be 18-37
middle-aged would be 38-57
old-aged would be 58-77

...or thereabouts.....
