Researchers are taking another look at gratitude and how a grateful mindset positively impacts mind a and body. Today is Thanksgiving in America. Not every country even celebrates Thanksgiving. One think for which I'm grateful is that the two countries I have lived in both have a special day earmarked--not the same day in each country, but a day nevertheless. Although Thanksgiving celebrations dated back to the first European settlements in America, it was not until the 1860s that Abraham Lincoln declared the last Thursday of November to be a national holiday in the United States. After the harsh winter of 1620 killed a sizable portion of the community, the American colonists reportedly decided to collaborate with locals in collecting food for the upcoming winter. It worked and in 1621 they had a potluck to give thanks for the abundance. If you're not "up" on Thanksgiving history, take a few minutes to watch a video clip or two. And find at least one thing for which to be thankful. It will positively impact your brain and body!
