Asian people generally do not have Rh-negative blood and hospitals do not store it for transfusions. Foreign travelers who have negative blood rhesus are in big trouble if they need a blood transfusion. There are so many ways in which Asians are different from other races and this is just one of them.

According to studies, Asians should not worry about whether or not they put deodorant after a shower, or before leaving the house. This is due to their special condition.

It's all about the "smell" gene.

No one is born with armpits that have an unpleasant odor. Our body produces odorless sweat, which is then "invaded" by bacteria.

However, a recent study from the University of Bristol has found that whether or not our armpits smell, it depends on a gene called ABCC11.

Initially, scientists thought that this gene was only responsible for the persistence of ear wax, making it dry or wet.

It was found that 80% to 95% of East Asian people have dry ear wax, while Africans and Europeans, wet.

Surprisingly, the durability of ear wax is related to the smell of the armpits.

It turns out that Asian people have a special genetic condition, which is the lack of the ABCC11 gene. This makes their ear wax dry because it lacks the substance that feeds the bacteria.

The same thing happens with their sweat: It has no smell. Bacteria stay "hungry" because the bodies of Asian people do not produce this substance for their food.

European and African people are not so lucky, as less than 3% of them do not have this gene, while the rest have it. This means that the bacteria have an environment to thrive, thus producing an odor.

Even though they find it unnecessary, many Asians continue to use deodorants, especially women.

Genetic science suggests that societal pressures are why many people continue to follow unnecessary hygiene routines simply because others are doing the same.
