harm that is done or sustained. The potential of injuring oneself or others can be increased after consuming alcohol due to the certain short term effects related to the substance such as lack of coordination, blurred vision, and slower reflexes to name a few. Due to these effects the most common injuries include head, fall, and vehicle-related injuries. A study was conducted of patients admitted to the Ulster Hospital in Northern Ireland with fall related injuries. They found that 113 of those patients admitted to that hospital during that had consumed alcohol recently and that the injury severity was higher for those that had consumed alcohol compared to those that had not. Another study showed that 21% of patients admitted to the Emergency Department of the Bristol Royal Infirmary had either direct or indirect alcohol related injuries. If these figures are extrapolated it shows that the estimated number of patients with alcohol related injuries are over 7,000 during the year at this emergency department alone. In the United States alcohol resulted in about 88,000 deaths in 2010. The World Health Organization calculated that more than 3 million people, mostly men, died as a result of harmful use of alcohol in 2016. This was about 13.5% of the total deaths of people between 20 and 39. More than 5% of the global disease burden was caused by the harmful use of alcohol. There are even higher estimates for Europe. Genetic differences Alcohol flush and respiratory reactions Alcohol flush reaction is a condition in which an individual's face or body experiences flushes (appears red) or blotches as a result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol. It is best known as a condition that is experienced by people of Asian descent. According to the analysis by HapMap Project, the rs671 allele of the ALDH2 gene responsible for the flush reaction is rare among Europeans and Africans, and it is very rare among Mexican-Americans. 30% to 50% of people of Chinese and Japanese ancestry have at least one ALDH*2 allele. The rs671 form of ALDH2, which accounts for most incidents of alcohol flush reaction worldwide, is native to East Asia and most common in southeastern China. It most likely originated among Han Chinese in central China, and it appears to have been positively selected in the past. Another analysis correlates the rise and spread of rice
