I'm sorry, but this is simply not true. As I'm sure we're all well aware, all generalizations are false, and this one is no different. Yes, it is true that the United States has an alarming number of obese citizens, but that doesn't make us "a nation of unhealthful overweights". And regardless, I know plenty of people who are overweight, yet are very conscious that their animals stay fit. Allowing oneself to become obese is, in most cases, a personal lifestyle choice, and I'd be willing to bet that the majority of people who do so are well aware of the negative effects on their wellbeing. Deciding not to care, and thinking it's okay, are two very different things. Just sayin. /endrant.
And OP, he's gorgeous. Haha! At least he's not going to cost you a bajillion dollars trying to keep weight on him :P
