I largely agree that one's reading should include non-fiction for the reasons you have stated but would also recommend including works of fiction, which enhance empathy, and because keeping track of multiple characters helps one's memory (particularly important for senior citizens such as I). Some consider poetry a sub-genre of fiction; if one's schedule cannot fit entire books of poetry one might consider reading rather than skipping the poems published in periodicals one already reads.
