Yes - I also didn't found the averages hard to interpret and not super full of insight. Presumably a lot of people spend 6-10 hours with their coworkers, and a lot of people spend 0 hours; a lot of people spend 8+ hours with their children, and a lot of people spend 0 hours, and pretty much the same for all of those categories. I'd have found a few 'typical' people in each age group more interesting. This is harder to calculate but maybe k-means clustering would be a good solution.
