In some motivation to look on the bright side, shutting down the inner pessimist could mean a longer life according to a new study which found that those who were strongly pessimistic about the present or future died about two years earlier than the average person. News24 reports that many people believe that looking on the bright side has positive outcomes, believing that seeing the glass half-full not only makes you happier, but also leads to a better quality of life and better sleep and the new research appears to confirm that. The researchers in this latest study found that pessimists tend not to take care of themselves and their health, resulting in their health declining more quickly than that of others.
