There are 3 things that have been shown to delay senility—reading, bilingualism and coffee. The delay may be as much as 5 years.
I need to look into it further. Also, I’d like to explore setting up some sort of ‘club’ around the practice of all three, perhaps at, or through, Otago Polytechnic.
I could start doing a regular workshop. I’d show people how to acquire another language the Unlearning way. It involves plenty of reading. And we’d take a coffee break or two.
Other factors could have an effect too, in which case additional activities could be considered.
