I won't go into detail--if you have a computer you can google it--but I read about 2 exciting advancements for Alzheimer's and dementia yesterday. More and more research points to your behavior assisting your own body systems to fight this scourge. Check out these proteins, BDNF and VEGF. They protect your brain, and are increased with good social support (is this a reason to party?), a lower calorie diet, regular exercise and good heart health. Make 2016 the year you're kind to your brain.

One of the gifts in this research is donation of brains of nuns and priests. The Religious Orders Study enrolls Catholic nuns, priests and brothers, from more than 40 groups across the United States. Participants are without known dementia and agree to annual clinical evaluation and brain donation (some in the Chicago area also agree to donate, spinal cord, nerve, and muscle). Now that's a way to have both eternal life, and to continue to serve in the temporal life.
