Great chart but what do I do with it?

On first sight I thought this is an intereseting bit of analysis and must have some marketing applications. The chart should be self explanatory.

On closer inspection, I am not sure what practical applications this knowledge has. Amazingly, the 75-plus seem to sleep over nine hours a day, so I guess you could say they are prime candidates for good beds. The 55-64 years olds spend over 2 hours a day doing “household activities” – I guess that must include cooking?

Anyway, for what it is worth there a pile more charts like this one on this site. Dick Stroud
