　　To minimize cravings（欲望）, change your routine.

Sit in a different chair at breakfast or take a different route to work. If you usually have a drink and cigarette after work, change that to a walk. If you' re used to a smoke with your morning coffee, switch to tea, or stop at Starbucks for a cup of java-the chain is smoke-free. You might even work better in coffee shops!

You can even do it yourself by taping "seeds" （small beads） onto the acupuncture points and squeezing them whenever cravings arise. Acupuncture can treat these other conditions, too.

　　Kim is one of many older people in South Korea-the country has the world's fastest growing ageing population. Almost half of the country's older people live in poverty. Some take low-paying jobs to support themselves after retiring. But Kim and some other seniors have shown how older South Koreans can find unusual job opportunities later in life.
