It may be a discussion of the way to __2__ in good health, or __3__ about how to behave and conduct oneself in society. If I cut the front article, the opposite one is likely to __4__ damage, leaving out half of it or keeping the text __5__ the title. Therefore, the scissors would __6__ before they start, __7__ halfway done when I find out the __8__ result. Sometimes two things are to be done at the same time, both worth your __9__.
