What will be the three simple sentence after breaking the big sentence?

Dear student
The three simple sentence would be-
For there is not any means by which those who have been born can avoid dying.
Proper sentence- There is not any means by which those who have been born can avoid dying
After reaching old age there is death.
Proper sentence- There is death after reaching old age.
Of such a nature are human beings.
Proper sentence- Human beings are of such a nature.

These small sentences make less sense than the whole long sentence untill and unless they are reformed properly.

Hope this helps!
Regards
