Although it was only a few seconds of spinning on the head, to do it right takes a lot of practice and time standing on your head abusing your cranium and brain parts. Everything was fantastic except the spinning on the head cause it could lead to brain injury called CTE. Chronic traumatic encephalopathy is a condition of brain damage which persists over a period of years or decades and which is the result of traumatic impacts to the cranium. The brain of an individual who suffers from chronic traumatic encephalopathy gradually deteriorates and will over time end up losing mass.
