January-June Not Good Timing
While M.D.s no longer use astrology in making diagnoses -- something that physicians did for centuries -- a massive meta-study involving over 86 million births in 27 localities worldwide has determined that there is a distinct connection between the season of one's birth and one's susceptibility to certain ailments and disorders. Those born in January, February or March, for example, have high rates of Alzheimer's, epilepsy, and bipolar disorder, while those born in April, May or June run the highest risk of glaucoma, multiple sclerosis and Parkinson's disease. The statistically safest birth months are September, October and November; the most disease-associated are March and April. Suggested explanations range from mothers’ vitamin D levels to seasonal bacteria fluctuations.
