Some people are naturally left-handed, and they are estimated to account for around 10% to 15% of the global population.
A study by Hamburg Medical School in Germany reports that left-handed individuals tend to be more competitive than right-handed people. The research suggests they may have a stronger desire to win in contests.
The study also notes that left-handers leave their mark in certain sports, where their competitive edge can stand out.
Earlier research has additionally indicated that left-handed people may excel in creativity and language-related skills.
