Isn't this old news? Go to Waianae and you don't need a scientific study. I'm not trying to be funny. My mom passed away when I was telling everyone to stop bringing her junk food. She was the last Hawaiian to pass away in her family of 11 siblings. Most Hawaiians live partying and drinking all the time because that is the lifestyle when you have so many friends and relatives. The kids get behind in education and end up filling up the prisons when they get older. It's hard to change their lifestyle even when someone close to them passes away from smoking, drinking, taking drugs or overeating.
