If the thought of getting up on stage and performing karaoke makes you feel like you're going to have a heart attack . . . maybe it's time to face your demons and just do it.  Because apparently, there's no place for heart attacks in karaoke.

--According to a new study, doctors found that occasionally performing karaoke can improve your heart health and your stress levels.  They found it eases tension and makes people feel happy and comfortable socially.

--NOW . . . keep in mind, this was a Japanese study, so you KNOW they wanted it to turn out pro-karaoke.

--But still . . . they studied almost 20,000 people and the results were statistically significant . . . so it's probably worth listening to.
