I used a 0.8mm pen for the larger dots to create an out of focus look and a 0.1mm pen for the finer details.

Runner’s high 🧬🤯 Since the 1980’s runner’s high was always thought to be caused by chemicals called endorphins. New studies now suggest that endocannabinoids are responsible. Endocannabinoids are a group of chemicals in the body that interact with the same systems in the brain that THC in cannabis does but your body naturally makes them. They are involved in soothing anxiety and reducing pain sensitivity. I personally find I get a strong feeling of runner’s high which is why I find running so addictive. Although achieving the feeling on long runs can put your mind and body through some intense suffering.
