There are more overweight persons now than in the dating/hook up market the past.

In a perfect world over weight persons would pair up with other over wight persons.

This doesn't happen in reality.

Many persons are not attracted to overweight people. Even if they themselves are over weight.

If we fix the obesity problem, there would be more attractive persons in the dating market.

Which could fix some problems in the dating/hook up market...... or make them worse.
