If you come by ZRT on Halloween you’re likely to be greeted by a witch, vampire, zombie or other nightcrawler. We take our decorations and dressing up seriously around here, and finding people in costume processing your labs or taking your calls is par for the course.

Driven by persistent exposure to stressors, the body begins to lose its dynamic resilience and fails to return the system to a normal baseline healthy state. Derailed and overwhelmed, our susceptibility to stress-related diseases is greatly increased [1].

ThinkstockPhotos-496639204.jpgAs we roll into 2016 what is it that YOU hope to change, reinvent, reconsider, move towards or away from in the coming year?
