This could be helpful to people who wants to enter some kind of jobs who need more height (like being a police agent in some European countries), but I find a huge thing for other reasons.

For what it means to dating, I think the requirement to be at least 6 feet tall for US women would disappear due to statistics (the mean male height in the USA is 5'9"). Heck, some guys who are 5'7" or 5'9" says to those women they are 6 feet and they believe it; It's more a psychological thing than a real preference as a have seen.
