Some people have a stronger desire to travel than others, and science may know the reason why.
Human behaviour geneticist Richard Ebstein has partnered budget airline Scoot to study the link between genes and people's desire to travel.
When people have an enjoyable experience, dopamine is released.
"What we have are many genes, such as this one, that can ever so slightly change our personalities and make us more likely to travel or develop a passion for travel," he said.
DRD4-7R likely plays some role in our desire to experience new things, but it is not the only factor, he added.
"Like all human behaviours, environmental factors influence just as much as genetic make-up," he said.
For Mr Chow, testing positive for the gene is good enough validation. "I can safely say that travel is in my blood," he quipped. ~The Straits Times 17th July 2018
