Is this to imply they think there is something "wrong" with men in their 30's?
Or is it simply a marketing technique that they think will make them look better or attract more lucrative clients?
Somehow I'm not inclined to believe that every guy over 40 is going to spend more money on this industry than every man under 30. Even though this might typically be the case, I'm sure there are exceptions out there.
Any providers who have this 40+ policy willing to comment? Opinions from others are welcome too.
