Holding liquor is not about how long one has been drinking or how much one has been drinking, and it certainly is not about training yourself to be a better drinker.
Because scientists have found an answer as to why some people cannot hold their liquor very well leading to some very erratic and impulsive behaviors.
According to the scientists it is because there is a gene mutation occurring in the body behind the inconceivable weakness to alcohol and impulsive behaviors.
The scientists believe that neurotransmitter serotonin 2b needs a receptor in the brain, and when there is a gene mutation this could mean that there is a lack of receptor or the other way around.
"The results also indicate that persons with this mutation are more impulsive by nature even when sober, and they are more likely to struggle with self-control or mood disorders," Roope Tikkanen, a psychiatrist at the University of Helsinki in Finland, said.
Serotonin 2b has yet to be full understood by the scientists, although it has been linked before to impulsive behaviors in past studies.
The study, which is published in online journal, Translational Psychiatry also reveals that the discovery of Serotonin 2b could lead to creation of new medications for impulsive behaviors.
The study also revealed that over 2.2 percent of Finnish people carry the mutated genes, which means that there are over 100,000 Finish people who can't hold their drinks.
But what actually happens to a person when drinking alcohol?
Other than Serotonin 2b giving their carriers a hard time, humans are naturally weak to alcohol for reasons that alcohol's major chemical, ethanol, is precisely engineered by nature to affect are brain once in the bloodstream.
Studies involving alcohol and their effects on the human brain and body have still a long way to go, but scientists are figuring it out and anyway it would be an enjoyable experiment to do.
