Apparently those adult beverages you and I enjoy are shrinking our brain, and even light to moderate alcohol consumption can cause the damage.
A study out of the University of Pennsylvania claims even one drink a day for women, two for men, can cause the brain to shrink causing effects of accelerated aging. This study shows that it's not just heavy consumption of alcohol that does damage, but that even light to moderate consumption has some negative affects to our health.
Researchers suggest to limit your consumption of alcohol to no more than one drink a day. Personally I love a good drink here and there, but I also spend so much time and money trying to slow the signs of aging that I think I'll take this one to heart and cut back.
