I just saw an interesting post onReddit with a list of questions you can customize for yourself when you are having a down day. Everyone has moments where they feel "down and troubled" as James Taylor says. With the creative liberty, we put together a list to help you know you've got a friend in us at IQed (not exactly as Randy Newman said, but close) 
"Instead of emphasizing one nutrient, we need to move to food-based recommendations. What we eat should be whole, minimally processed, nutritious food—food that is in many cases as close to its natural form as possible." ~Dariush Mozaffarian, dean of the Friedman School of Nutrition, Tufts University and adjunct associate professor of epidemiology 
Regardless you'll want to get you and your family up and walking in nature at least for 30 minutes based on a new study led by The University of Queensland (UQ) and the ARC Centre of Excellence for Environmental Decisions (CEED) who suggest people might need a minimum “dose of nature”.

"It's never too late for good nutrition" ~ Dr. Jianghong Liu, an associate professor in Penn's School of Nursing and Perelman School of Medicine. The main finding of a new study from two University of Pennsylvania researchers has found proper
nutrition during childhood can positively affect a child's social behaviors, friendliness, extent of verbalization, and development. The results are published in the journalMaternal and Child Nutrition.
