Can you die from too much sleep?

"the scientists found that sleeping more than 7 hours a night may also be bad for us. Among the civil servants who increased their nightly sleeping period from 7 hours per night to 8 hours per night or more, the overall mortality rate more than doubled! In this case, cardiovascular problems did not seem to be the main cause of death. The scientist are still trying to establish what lies behind these findings, and what is the true reason for these high mortality rates in well-rested people. In any case, based on these results, it seems clear that sleeping too much is also not recommended. "
