At our house, Thanksgiving is about telling family stories and sharing anecdotes. This is what I love best about getting together anytime with the family. Usually I start stories off as narrator. Now the kids continue telling them with embellishments. Silly family stories make us feel good. In fact, we keep arteries healthy with optimism. A Harvard study found that upbeat people are 50% less likely to have heart disease than their gloomier counterparts. Why? Their bodies produce far fewer artery-damaging stress hormones.
