No Sickness

A young man under thirty will not be sick. Even 30 to 40 also no sick. It is become their blood circulation running fast, digestion fast.
But, if your age is over forty, and you live an unhealthy life. Your chance to be sick will be more.
Still, if you take rest and ever you do not see doctor and take medicine, you can recover by yourself, by your own body resistive.
When over 50, your energy is downwards. If you still live more night life, drinking nightly, smoking non-stop then you will be sick.
Such like heart attack, high blood pressure, all of which will come by themselves, ever doctors cannot cure you.
At too, gone days near, living days less. You have to take much care about your sickness, high illness many take your life away.
Seventy is for most people to live. Only 80 is the age for people to face risk of death. Of course, still some people live to 90 or higher.
