It seems that some people use coffee as, say, a stimulant to try to deal with ADHD. I wonder how much this self-medication impacts the results. Perhaps unusually, I recently did a little self-inventory and decided to consciously up my coffee consumption. At this point it seems to have a good effect on my ability to concentrate, and I could see this improving other health outcomes as it increases follow-through on exercise etc. (Caffeine may also reduce DOMS symptoms, again allowing for more exercise. http://www.ncbi.nlm.nih.gov/pubmed/24164961 http://www.ncbi.nlm.nih.gov/pubmed/24164961)
