Last week, we reported that a study had revealed that younger siblings are funnier on average.
Well, it's good that they can make people laugh since it now turns out the first-borns got the smarts.
A study by the University of Edinburgh and the University of Sydney observed over 5,000 children from pre-birth to 14 and found that first-born children had higher IQs from as early as one year old.
Don't worry, young ones. We won't forget about you when we're "enjoying better wages."
