BBC NEWS | Health | Sisters 'make people happy': "Sisters spread happiness while brothers breed distress, experts believe.

Researchers quizzed 571 people aged 17 to 25 about their lives and found those who grew up with sisters were more likely to be happy and balanced.

The University of Ulster said having daughters made a family more open and willing to discuss feelings.

They said the influence of girls was particularly important after distressing family events such as marital break-ups."
