fatness in Mexico is getting so bad that not fat girls are treated like royalty and behave as such. Since I now live in a place where pretty girls are more prominent they are more down to earth, ergo my dating situation has improved.  This is why obesity and bad habits impose a societal cost.   Additionally, being around non-hideous people is akin to the environmental difference between a tree-lined boulevard and prison.  Does environment affect your sense of well-being?  Of course it fucking does (for example, people in low-density areas are happier).   So not only does widespread obesity ruin dating, it has other psychological effects.
