Poon Ho Chuen completed this course and found the course difficulty to be easy.
An eye-opening course! You will know how diet (insulin resistance actually), meditation, sleep and exercise affect your brain. And full of reference article.
Some of the points are controversy, for example, the instructor says there is some benefit on cognitive exercise. However, other psychologists may not agree with this point.
I hope the instructor can share more her personal stories in biohacking her brain.
