I was just going to post something like this. Bloody stupid comment @@Happy101010 
Physically very attractive people get cheated on all the time, and physically attractive/very good looking couples split up all the time too.
Weirdly, some of the most solid couples I know (who have been married/ together 25-30+ years,) are not super-glam supermodels. Some are quite plain, and some are quite overweight.
The ones who are 'typically' physically attractive (what society deems as physically attractive anyway,) seem to go from one shitty failed relationship to another. And I know a few women, who were classed as the 'pretty ones' at school, and when they were younger, and were super popular with the boys, who are now middle aged and single with 2 or 3 kids from different dads. And as I said, not one single successful relationship - ever.
In addition, their looks are pretty much faded, and they're constantly desperately searching internet dating sites for a daddy for their kids a man. Whilst the (supposedly) less attractive/less fit and glamourous people are very happy and still with the person they met 25-30 years ago.
So it's bollocks that more attractive people will get - or actually DESERVE - a successful relationship,
