Man is a three dimensional being. He is a spirit, has a soul and lives in a body.
The body is a great blessing from God.
It is through our body we make physical contact with the world around us.
Without the body, it'll be practically impossible to be physically existent on the earth.
...and we have just one body, there's no spare.
That's the reason we must take care of our body with all we've got.
Never seek or pursue wealth at the expense of your health.
Simple daily personal hygiene can make the body last longer.
Eradicate or minimize exposing the body to hazardous environments, weather, chemicals or instruments.
As much as possible, eat balanced diet and engage in moderate and regular exercises. Remember, you are what you eat.
Avoid those negative habits which obviously have detrimental effects on the body.
These things amongst others, would help you keep a healthy body that can stay around for a while.
