I tried a quiz in the website https://www.brainhealthassessment.com/ by Daniel G. Amen, MD. And my type was the brain type 5.
The traits of the brain type 5 is below.
- Cautious
- Prepared
- Motivated
- Busy Mind
- Can Have Trouble Relaxing
I feel it is correct.
As a reference, his book: Dr. Daniel Amen - CHANGE YOUR BRAIN - CHANGE YOUR BODY - Appendix B also shows the questionnaire.
