I often throw in how important is mental acuity to the overall body functionality. Especially at this time of year when getting large groups of family together, I thought about giving everyone an excellent mental exercise that they can use while *ahem* sitting around and eating at a table (just watch those calories, ok?)
positive psychology? ACR is Active Constructive Responding, and the basic premise is to promote only positive responses to outside stimuli. There is a good test at the PBS blog to give yourself cues on when to use this technique.
Stay positive, enjoy your families and your time off from work to reduce stress and change your routine. Then feel energized and ready to return to your normal grind and workout, possibly with better tools than before!
