Blood types overlap quite a bit between the races, though most of the world is Rh positive while about half of Europe is Rh negative (Sykes, 2001, p. 41). The races differ significantly in the percentage of their populations that fall into the different categories of the various systems for classifying blood (Baker, 1974, pp. 185-187). Some blacks have rare blood types found only in blacks and, to avoid incompatibility, they may be advised to receive blood transfusions from blacks having the same type. Treating a person of one race as though he were a member of a different race can lead to serious medical problems or even death. The number of red corpuscles and the amount of hemoglobin in the blood, the pulse-rate, the vital capacity [lung capacity], the muscular strength, the amount of urea in the urine, are different in different races. Most populations below the Sahara average 60% of the Rho subtype which is found in only 2% of whites. Absence of the Duffy factor (Fy) in blacks, common in other people, is responsible for their immunity to vivax malaria (Pollitzer, W.S., The Gullah People and their African Heritage, 1999, p. 15). There are scores of different tissue types that have a genetic component and differ among the races (Sykes, 2001, p. 91). The races have different bacteria in their bodies (Caufield, 2007), e.g., different vagina flora and fauna, and different parasites, e.g., a different species of body mite inhabits the bodies of East Asians and Europeans. There are racial differences in reactions to foods, drugs, and other substances (Bailey, 2005). In June of 2005, the Food and Drug Administration (FDA) approved the sale of BiDil, a drug that reduces damage to the heart in African Americans, but has little effect on Eurasians (Liggett, 2008). The FDA specifically permitted its sale to be directed at blacks. GenSpec Labs, LLC is even marketing race-tailored vitamins, specially designed to meet the needs of African Americans, Hispanics, and Caucasians. There are racial differences in susceptibility to various diseases, even neuroses and psychoses, but especially debilitating diseases, such as cancer, and genetic diseases (Holloway, A., 1996). For example, whites have much more melanoma (skin cancer) than blacks, but far more blacks have a deadlier form of it (Hu, 2006). African Americans are more than twice as susceptible as whites to developing prostate cancer by age 55, and that is due, at least in part, to a gene variant in chromosome-8 (Freedman, M.L., 2006). Blacks are also more susceptible to tuberculosis (Stead, 1990). Northern Europeans, on the other hand, are more susceptible to cystic fibrosis. Two well-known racial genetic diseases are sickle-cell anemia in Africans and Tay-Sachs disease in European Jews, but there are many others. In fact, the number of medical differences between the races is so great that it would take an entire book just to describe them all. A black medicine specialty is arising and there is even a journal, Ethnicity and Health, devoted to medical differences between the races. Blacks at Howard University have started a program to identify genes unique to blacks so that medical treatment can be specifically tailored for blacks. To argue that "race" is just a social concept when the human body reacts differently to chemical and biological substances and infectious organisms depending upon race, illustrates how nonsensical that position is.
