the secret of longvity

I love eating fish very much.I feel lucky that there are so many kinds of fish.and i can have a huge variaty to choose from them.it is said that in one island of japan,the rate of people over 100 is much more than other place because they eat a lot of fish and rice.meat on the other hand,is not good for your health if you eat them everyday.so,eating more fish instead of meat or beef is a good choice if you want to enjoy a happy and healthy old age.so,what about you,do you love eating fish?what kinds of fish do you enjoy?
