Matured children really make their parents happier if they live separately from them, Plos One reported referring to specialists from the University of Heidelberg, Germany.
Scientists analyzed data from the European Social Survey regarding the emotional state of 55 thousand people aged 50 years and older.
It turned out that parents of this age category were more satisfied with their lives and were less likely to suffer from depression compared with the peers who did not have children.
Meanwhile, such positive feelings were achieved under one condition: their adult children were independent and lived separately.
Scientists attribute this to the fact that moving children relieves parents of the stress associated with caring for them.
