What is the most important thing in the world？I think it is health．You can take away our money，house，car，or even our clothes and we can survive （生存）．But （112） if our health is taken away ， we will surely die．This is why we always try to eat in a healthy way and exercise regularly．

（113） Taking exercise every day helps us build a strong boby．We should do sports for half an hour or forty minutes every morning or every evening，such as going for a walk，playing basketball or football，swimming and so on．

To keep healthy，I have another idea：don't overwork．Too much work will be bad for you．
