A new study has just discovered that reading has an important impact on people's lifespan. Over the course of the study, the researchers ＿＿（16）＿＿ found that the readers lived longer than the non-readers. The readers who read over 3.5 hours a week lived a full 23 months longer than the people who didn't read at all. That extended lifespan applied to all reading participants, ＿＿（17）＿＿ "gender, wealth, education or health" factors. That's a 20% reduction in ＿＿（18）＿＿ created by a sedentary activity. The researchers stated, " ＿＿（19）＿＿ non-book readers, book readers had a 4-month survival advantage" at the age when 20% of their peers passed away. "Further, our analyses demonstrated that any level of book reading gave a significantly stronger survival advantage than reading periodicals. This is a 20 finding, as previous studies did not compare types of reading material; it indicates that book reading rather than reading in general is driving a survival advantage."
