Ok,I don't know how to ask for help but I have summarized one paragraph. Please someone check it and let me know If I've done it right.
the original Paragraph:

Sample Précis: Aristotle on the Character of Those in the Prime of Life Original Passage (199 words) "It is evident that those in the prime of life will be between the young and the old in character, subtracting the excess of either, and neither exceedingly confident (rashness is such) nor too fearful but having the right amount of both, neither trusting nor distrusting everybody but rather making realistic judgments and not directing their lives only to what is fine or what is advantageous but to both and neither to frugality nor to extravagance but to what is fitting. Similarly in regard to impulse and desire. And they combine prudence with courage and courage with prudence, while among the young and the old these things are separated; for the young are brave and lack self-restraint, the older prudent and cowardly. To speak in general terms, whatever advantages youth and old age have separately, [those in their prime] combine, and whatever the former have to excess or in deficiency, the latter have in due measure and in a fitting way. The body is in its prime from the age of thirty to thirty-five, the mind about age forty-nine. Let this much be said about the kinds of character of youth and old age and the prime of life." (Aristotle, Rhetoric, Book Two, Chapter 14. Translated by George A. Kennedy, Aristotle, On Rhetoric: A Theory of Civic Discourse. Oxford University Press, 1991)
And now the precis:
The beauty of Prime age
the author explains the significance of prime age. It is the time when one is past the immature phase of youth and away from the reservations of old age. People in their prime have the very best of both worlds. they have the stamina of youth and the stability of age and are thus more likely to form sound judgement.the prime age for body is from thirty to thirty five while that of the mind is forty nine.
