Three Sets or Five Sets?

Is it time for the women to show their true grit in major finals? Men play best out of five sets for all matches in majors. I think that would be too much to ask of the women for various reasons. Their rallies usually seem on average to be longer especially for the defensive player's matches ( I do not have the stats it is just by observation). Women are born with about thirty percent less muscle mass than men. Be that as it may I would like to see the fitness of the women tested to a higher level in major finals. This would also without retirements or ? guarantee that we would see at least three sets in the major finals on the women's side. When someone wins in straight sets now it's just too short for a major match. Think of some of your favorite players that you might watch for five sets if this change takes place!
