The Maori war dance (the haka) and being bilingual may help to keep dementia away. A study looked at dementia in people in their 80s and 90s. Maoris have less health care, less income and more heart diseases than non-Maoris. The researchers found no differences between Maoris and non-Maoris.
The haka is an old war cry. People chant and stamp their feet. Warriors did it before battles to show their strength. The famous All Blacks rugby team started using it in 1905. The All Blacks now do it before all their matches. A professor said that the thinking about and doing the haka help to keep the brain healthy.
