The numbers are a bit skewed by age and make some odd assumptions. For instance an 80 year old [no I'm not THAT old] would have spent more years in a neighborhood where not 50% had college degrees. Also the Operations Manager might go on a factory floor everyday but have a different experience than a person on an assembly line. Going fishing might be with a cane pole or from a party barge or nicer.
All that said, it is fun and probably does reflect something about one.
