I have come across to this website. The one that author Bill Perkins suggested us to check it out in his book “die with zero”
Based on your diet, exercise, age, family history the test will give you an estimate and also suggestion. I am not sure I will want to live till 100 though.
Here is the suggestion they gives you after. I never thought of doing bran enhancement activity like sudoku. Considering there is dementia history in the family, perhaps it’s a good idea to do so.
It’s interesting. Give it a go
