Although you math is correct, you question is flawed. This would require him to spend 22 years as a boy and 11 years as a youth. When is the last time you heard a 33 year old man called a "youth" or a 22 year old a "boy".
When his wife was telling her friends about him behind his back, next question dave!
Also, what if there was a stage in between being an active man and an old man...?
I would attempt the problem by considering the "youth" time to be included in the "boy" time, as anyone I'd consider a boy I'd also consider a youth.
Basically, it's a good teaser. the proportions of the life stages were somewhat off, but most people would concentrate on the math. Next time you do an age problem, think through the realities of the parts of the problem. All in all, though, the teaser is a good one; please do more like this.
