The Private Man points out how difficult it’s not.
What are the differences between the two photos?
- Grooming (especially the hair)
- Skin (probably due to healthier diets)
It’s not complicated. The food, hair, and clothes aren’t free, but they aren’t so expensive as escapism.
Another important element to physical attractiveness is your tone of voice, which the picture can’t demonstrate. Men should aim for a healthy, attention-demanding baritone and women should aim for a wistful soprano (unless she’s disciplining the kids, obviously). Imagine the better examples of Italian men and French women, respectively.
There’s also a preselection effect from the romantic way they’re standing together. When you consciously notice it you’ll get a little uncomfortable, but it’ll be outweighed by how happy you are for them.
