We are human. From childhood up to our old age, we wish to have a peaceful life, away from trouble and disaster. But, this is not easy. In this world today, there are a huge number of people, wounded, or killed in the accident.
We cannot resist accident from nature, such as earthquakes, flood, or mountain slide and so on. But, we should, within our wisdom and ability, avoid to create any accident by our own to be away from regret forever.
Some of young men nowadays, especially those jobless persons wandering in the street of big cities, are easily inclined to fight just for very minor affairs. As a consequence, he may hurt other person or he may be wounded himself. Both ways are of disasters in the end.
Also, some young people like to drive car race, climbing cliffs, parachuting, boxing, deep sea diving, etc. All of those sports are dangerous. But, it is their own choice and no one can interfere.
Middle aged men hurt themselves by over drinking of alcohol and spend their time on the night club even late at night. As a consequence, they shorten their lives.
Only old people are more careful about their lives. They know that to live long is not easy. Even their lives may not be very happy, but they still try to live as long as they can.
