Guess you would expect me to say eat a well balanced diet, exercise regularly, drink alcohol in moderation and don't smoke Laughter is also a good medicine Having a positive attitude does help - the optimist sees the doughnut, the pessimist sees the hole
But there's also an element of luck ...it's in your genes (have your parents lived to a good age?), you may be lucky to have good friends and supportive family. We all know people who look young but seem to live unhealthy lives ! Bahala na
