My rules for living longer:

-Low carbs, lots of fresh stuff from the garden.
-One meal each day needs to be a big salad. Except Sunday.
-At least once each week just eat for a three hour period.
-Feast every Sunday.
-Keep moving, don't sit too much. I get a lot of exercise from walking with Ginger Granny and from my gardening.
-Be grounded, I almost always barefoot.
-Don't use aluminum or nonstick cookwear.
-Always have a plan for the next year
-Keep your mind active, I research conspiracies and do Sudokus. I should also monitor another class at Ohio Univ. Also I have been researching the Hopewell Indian culture, there is a dude from OSU that is the world's authority, I need to go to a lecture of his someday
-Be kind to your colon. Eat lots of roughage.
-Every now and then learn a new activity that will create some new nerve pathways in the brain. This year I tried to learn how to play the piano but I'm hopeless, music is beyond me.
-When you are young you should do some long distance running to get your heart big and strong. Lifting weights will help your bones to grow thick. Always eat enough. I see too many young girls today that have a cylindrical rib cages, that's not healthy.

But in the end genetics rule. Watch Hogans Heroes and look at General Burkhalter, that obese fellow lived to be 99. Adrenachrome might have been part of that though.
