¢ “Move naturally. Be active without having to think about it.”

¢ “Hara hachi bu. Painlessly cut calories by 20 percent.”

¢ “Plant slant. Avoid meat and processed food.”

¢ “Grapes of life. Drink red wine (in moderation).”

¢ “Purpose now. Take time to see the big picture.”

¢ “Down shift. Take time to relieve stress.”

¢ “Belong. Participate in a spiritual community.”
