I was just browsing the page on incidence of PD by county and noticed that Japan is the only country where women have a higher incidence than men. Interesting. I googled what do Japanese women do that men don’t and came up with what they eat for breakfast:
Interesting that the men eat traditional food like miso soup and natto while women tend to choose more western breakfasts.
Having said that they don’t come at the bottom overall by incidence, but that might be because they are the longest lived people so more people reach old age. I wouldlike to a see an incidence by age study.by country.
