OK, this post is from a girl...but, there are studies available relating to the restriction that the male anatomy suffers in "briefs" type underwear...that is why couples with fertility problems are often advised to have the husband try boxer shorts.
SO, based on this, I'd have to say that kilts are right up there on the top of the list for garments that promote all-around male health and well-being.
Therefore...buy more kilts!! Your doctor may even want to write you a prescription! AND, for those of you who have had problems with being kilted at work, tell 'em that it fits into the employee wellness policy.
