A recent study has found that those who have sisters are more likely to lead a happier life. The study from De Montfort University and Ulster University found that even though they may drive us crazy from time to time, having a relationship with them is hugely beneficial.
"Sisters appear to encourage more open communication and cohesion in families. However, brothers seem to have the alternative effect. Emotional expression is fundamental to good psychological health and having sisters promotes this in families."
"It could be that boys have a natural tendency not to talk about things," they added.
"With boys together it is about a conspiracy of silence not to talk. Girls tend to break that down."
"With only children we found that they had lots of strong communication outside of the home. It appears that they have as much social support as those with siblings, but it does not come from within the family."
So if you have a sister, it might be a good time to thank her for all the work she's unintentionally done over the years to make you a better person!
