According to a new study, first-born sons are 24% more likely to work in executive positions than second-born siblings, and 28% more likely than third-born siblings. According to the research, the eldest children in the family are also more emotionally stable, outgoing, persistent, and responsible than their younger siblings.
Younger siblings, on the other hand, are more likely to be self-employed.
I'm seven years older than my brother...I'd like to think that I'm the more stable, responsible child...he may disagree, but what does he know? ;)
