Hmmm... I try my best not to judge people on looks. I think it is part of the overall package yet as I left my 20's I found I was much happier with women who I judged on compassion and intelligence primarily and looks secondarily.
In high school I hung out with the football players and quite a few gave me grief for dating a girl they felt wasn't beautiful... She was kind, smart and I thought she was beautiful so I ignored them.
Another, it depends answer. At my stage of life I wouldn't expect a playboy bunny (ugh, nor would I). I judge by how healthful a person looks AND takes care of themselves.
It all depends on how much you value appearances..... I recall many years one day in June when I was in Hyde Park London a man approached and sat down on the park bench where I sat.. It was obvious from his appearance that he had been living on the street for a very long time. His hair was long and matted together and he stank. However, when he spoke it was clear to me that he was very well educated and it turned out he had been to Eton and studied philosophy at Oxford University. Had I arose and walked away when he arrived I would have missed a great conversation, which, I doubt I would have experienced with any of the casually and well dressed people who walked by us that day.
Everyone takes an initial first impression of everyone else in order to asses potential danger, it is a survival instinct.
However once interaction takes place a deeper assesment is made based on personal preferences, social norms, compatibillity of opinions and threat assesments.
We all make judgements based on all sorts of things, including appearance, mannerisms, what music the person is listening to, gait, and more. Whether or not one draws conclusions about the person prematurely based on those observations and judgements is really the issue. I think some of us tend to do so, while others do not. I would like to think I am part of the latter group.
I have just noticed you are in London. I think perhaps city people care more about appearances than country people, so that may be another factor!
I am in London, but I try not to judge anybody....especially not for their appearance. I am more countryside loving person , than a city girl.
Totally off-topic - is that Highbury Fields?
Victoria Park?
No cigar for me
If appearance is the only thing to go off, then obviously no it is not possible, otherwise yes.
