People have propensities towards different looks or ages. I know some girls that will always fall for a cool dudes with stubble and a shabby look. Others will be infatuated by a sight of decent well groomed men. It is not a big deal. You shouldnt put too much into whether falling for a particular age group is perturbing. All these love stories have their roots in the looks whether people admit or not. You just be a good evaluator of what kind of life partner you want, and apply the evaluation when you fall for somebody’s looks.
