It is ok to divorce your wives if they become old and fat, unless they give their turn for sex to someone younger

Abu Dawud vol.2 no.2130 p.572

When Sauda was old she was afraid Mohammed would divorce her, so she gave her turn to ‘A’isha.

So who was Sauda?

Bukhari: Volume 6, Book 60, Number 318:
Narrated Aisha:
Sauda (the wife of the Prophet) went out to answer the call of nature after it was made obligatory (for all the Muslims ladies) to observe the veil. She was a fat huge lady, and everybody who knew her before could recognize her. So 'Umar bin Al-Khattab saw her and said, "O Sauda! By Allah, you cannot hide yourself from us, so think of a way by which you should not be recognized on going out. Sauda returned while Allah's Apostle was in my house taking his supper and a bone covered with meat was in his hand. She entered and said, "O Allah's Apostle! I went out to answer the call of nature and 'Umar said to me so-and-so." Then Allah inspired him (the Prophet) and when the state of inspiration was over and the bone was still in his hand as he had not put in down, he said (to Sauda), "You (women) have been allowed to go out for your needs." (it was because of Sauda's that the veil was forced on all women - http://muslimhadith.blogspot.com/2008/04/hijab-was-revealed-because-umar-wanted.html)

And what did Allah say about this situation, where Mohammad did not want to have sex with Sauda anymore?

Quran 004.128 YUSUFALI: If a wife fears cruelty or desertion on her husband's part, there is no blame on them if they arrange an amicable settlement between themselves; and such settlement is best; even though men's souls are swayed by greed. But if ye do good and practise self-restraint, Allah is well-acquainted with all that ye do.
(In other words, Allah approved Sauda giving up her sexual turn to Aisha)

1) Does this mean that women should start getting in better shape in their old age to make sure that their husband's don't threaten to divorce them, or starting giving up their turn?
a) Does Allah's Apostle encourage the use of Botox?
b) How about liposuction?
c) Would Allah's Apostle have accepted Sauda if she got liposuction, botox and plastic surgery?
d) Is Prophet Mohammad's dreamgirl Pamela Anderson?

2) Once again Allah's Apostle's sexual desires are met http://muslimhadith.blogspot.com/2008/08/allah-works-to-make-sure-mohammads.html:
a) Could this be a reason why the oversexed Prophet had so many semen stains? http://muslimhadith.blogspot.com/2008/05/mohammad-had-lots-of-semen-on-his.html
b) Did Mohammad need to make sure he not have sex with Sauda anymore so that he could keep up his sexual strength of having a sexual libido of 30 men (being the greatest lover-prophet ever)?
Bukhari,Volume 1, Book 5, Number 268: “Prophet was given the strength (sexual) of thirty men”.

3) Is this why Aisha liked Sauda so much, because she did not have to compete with her for the Prophet's sexual attention?

4) I once had an argument with Mr. Himed who told me that Prophet Mohammad was charitable for marrying Sauda... http://muslimhadith.blogspot.com/2008/08/response-to-mr-himed.html
a)The question that now needs to be answered is why Mohammad married Sauda in the first place? She was a widow that took care of his children after Khadija died, and 3 years before he could finally have sex with his child bride Aisha.
b) Does this mean that all of Prophet Mohammad's actions were sexually motivated?
i) The minute Mohammad no longer needs a women, he discards them?
ii) Mohammad needs women to constantly beautify themselves? http://muslimhadith.blogspot.com/2008/08/muslim-must-have-hairless-palms-and.html

5) Does Abu Dawud include this hadith to show what type of morality Mohammad had?
a) After all, Abu Dawud states that divorce is detestable for Allah, where Mohammad divorced many women, and that in this case, he did not divorce Sauda only because she gave up her turn to Aisha, despite knowing how detestable this action is for Allah?

Book 12, Number 2173:
Narrated Abdullah ibn Umar:
The Prophet (peace_be_upon_him) said: Of all the lawful acts the most detestable to Allah is divorce.

b) Does this mean that Allah's Apostle never cared about what Allah thought about, especially when it came to satisfying his sexual desires?
