I'm looking for references for the norms of a young adult's sleep, elimination, hygiene, nutrition, physical exercise, hobbies, interpersonal relationships, environmental safety, and personal safety (risk for falls, etc). I get the overall gist but need research to support my paper. So far I've only found what an exercise routine SHOULD be like (not what norms are), but I've only started researching today (paper's due in a couple weeks).
