Wow! I just read about the benefits of origami at https://www.redtedart.com
This is what they had to say:
In a nutshell, Origami is good for you as it develops eye hand co-ordination, sequencing skills, Maths reasoning, spatial skills, memory, but also patience and attention skills. Origami allows you to develop fine motor skills and mental concentration. All of this combined stimulates the brain – especially when BOTH hands are being used at the same time.
