Washington, April 18 : A new study conducted by Stony Brook University researchers suggests that feeling bored in marriage leads to substantially less marital satisfaction even nine years later.

Research leaders Irene Tsapelas and Arthur Aron, who worked in collaboration with University of Michigan researcher Terri Orbuch, interviewed 123 U. S. married couples seven years into their marriage, and then again, nine years later, 16 years into their marriage.

According to the findings of the researchers of the Kansas City University of Medicine and Biosciences, mothers-to-be who exercise during their pregnancy term give birth to healthy babies, with their lungs and nervous system strengthened in the womb.
