Blame it on your mother. And father. And for that matter, your grandparents. If you hate to exercise, it could be in your genes. Specifically, genes that modulate the dopamine (a feel-good chemical) in the brain appear to play a role in our propensity to embrace or avoid exercise, according to researchers from the University of Georgia. You just have to look at any group of people to know that some exercise frequently, while others prefer the couch. Now it appears that the part of the brain that drives rewards and the part of the brain that drives the motor system are interacting, causing some of us to want to run a marathon and leading others to binge watch “Game of Thrones.” Translation: Gym rats get a rush from working out as dopamine levels soar, while couch potatoes appear to have a genetic makeup that interferes with the release of dopamine.

The American Heart Association says the ideal amount of sodium is no more than 1,500 milligrams. Now the CDC report has found that Americans typically consume 3,400 milligrams of sodium daily–more than double the ideal amount.
