But models, what did they earn? They were genetically given that body. Fuck that.
But do note that your very intelligence is something you were genetically given. Now, it might well be that you worked hard to achieve your high level you hold in it, but do not those that have the pinnacle of physique also work towards it? If one says that the physical body you possess is something you are given, then so is the mind. And if the mind is something you must work towards, so is the body. Of course, and you know this, it is balance, and not having one out of measure with the other, that is the truly desired mean.
Of course, I do understand your frustration, and it's an old one. Take solace in Socrates as your companion. You see, when he was on trial for corrupting the youth, and he was asked what he thought his sentence should be, he suggested free meals at city hall. Now, this might seem overtly seem a certain levity for the jugement rendered against him, but instead it is a profound comment on this very thing. You see, it was the athletes who, having had an Olympic victory, were entitled to a lifetime of free meals there. In stating that, for upsetting the city with his observations, making people think, etc. he should receive the same luxury, he was essentially stating that his effort on behalf of the intellectual good of the populace was as, and indeed more, beneficial than that which the athletes gave the city. This was actually the topic my Graduate supervisor spoke on when he was the speaker for the year end get-together in the department a few months back. So if you're feeling frustrated, remember that just beside you, calmly drinking the hemlock, is Socrates.
Just another note about model sorts... that need not always be the case. For example, a recent acquaintance of mine. Judging by some of her pictures on Facebook, she seems to have, a while back, done a shoot of modelling. I've not asked her about it, but judging by the captions it was for some jewellery catalogue or some such thing. I must say, she looks absolutely stunning - to match with the best, in my opinion. All the same, from the context in which I got to know her, I know her as probably the most brilliant person my age I've ever met. Extremely passionate about her studies, these being Classical linguistics (alright, maybe I'm biased because of this, heh), someone of apparently remarkable ability and extreme love of the subject. To top it off, she has had some time in the field of astrophysics. Plainly here is someone of extreme ability and intelligence - I will lightly say far outmatching my own, and that is not a judgement I typically make so surely.
Of course, that does not excuse the dim wits that populate Facebook. I share your agony.
