Im researching for my dissertation, at derby uni in england. Im gonna do concentration and memory tests on people during exercise to see behavioural traits shown, compared to influences of drugs on people, opiates such as morphine and heroin. Any help would be great, stuff on those chemicals or exercise addiction, Journals, past exercise tests, and ideas. Thankyou
