Kamada Nakasato, 102-year-old female from Okinawa, Japan, says to eat your vegetables, have a positive outlook, be kind to other people and smile. Sounds like good advice! Long-life secrets are leading scientists at Boston Medical's New England Centenarian Study program to also look at the combination of our genes.

Over the Fourth of July holiday, our nation's oldest citizen, Gertrude Weaver, 116, from Camden, Arkansas said the secret to long life is: "Kindness, treat people right and be nice to other people, the way you want them to be nice to you." Ms. Weaver delights in weekly manicures, Bible study, 'wheelchair dancing' called "Sittercise" and concerts by local singers.

So, how old would you like to be at the time of your passing? Well, here are some predictors for reaching 100: Few centenarians are obese, smoking history is rare, they are able to handle stress better than the majority of people, many have given birth after 35 to 40 years and excessive drinking is uncommon. I'll drink to that! Let's toast: May we live a long life full of gladness and health. Cheers!
