Alcoholism is linked to many biological factors, some of which are hard to believe. The color of your eyes may be a factor in determining whether or not you’re likely to become dependent on alcohol, a study finds. A team of researchers discovered that people with lighter colored eyes had a higher risk of dependance in comparison to people with dark or light brown eyes. According to researchers, the findings could be significantly helpful for the future of alcoholism research. Blue eyed people have it the worst in this case.
