You obviously know the cliché "laughter is the best medicine."  Researchers at the Universities of Oxford and Birmingham in England wanted to find out if there's any truth to the statement. The study did find some situations where laughter is an important part of the medical process like patients whose conditions improved when clowns went to the hospital. But they also found a lot of cases where people had suffered from bad asthma attacks, ruptured their hearts, tore their throats, or lost control of their bladder functions because of laughter.  RUPTURED HEARTS!?!? I NEED to hear that joke!  The overall results on their study say laughter probably won't have an effect either way.
