In The Dilemma，Vince Vaughn’s character is keeping a huge secret from his best friend: His wife is cheating on him. Vaughn’s “dilemma,” of course, is whether or not to tell his buddy. But, he may not know he’s also putting himself in harm’s way by lying to his friend. Guilt is just the beginning.
Along with guilt, people who lie, omit the truth or keep a secret are at risk for some not-so-pleasant health complications. For starters, lying releases stress hormones – the same ones that are triggered in what’s called your “Fight or Flight Response,” This increase in stress hormones causes your heart rate and breathing to increase, digestion to slow down, and hypersensitivity of muscle and nerve fibers,” she says.
These affects may not sound that serious, but over time, they can lead to conditions that no one would want, such as coronary artery disease, stroke, and congestive heart failure. Why? Because blood pressure rises in the heart when you’re lying, “which can be life threatening over a prolonged period of time,” says Dr. Smith. (This is why Polygram or lie detector tests accurately test for lying, because they measure jumps in blood pressure).
Frequent truth telling made lying more difficult, and frequent lying made lying easier.” 诚实人很难撒谎，常撒谎的人说谎容易。
