Chastity
The appeal of chastity has waned considerably in the modern era. This is because chaste persons don't have sex--not even on their lunch breaks. The advantage to living chastely is that one is permitted to love indiscriminately all of humankind. This is not ordinarily possible, unless you own a king-sized bed. Chastity harnesses our baser impulses and channels them into mission and duty, even when we are off the clock.
There are not many people practicing chastity today. The commercial secularism of the industrial societies has all but relegated the concept an anachronism from more religious times. Most chaste people do not begin that way, but rather are driven to it by husbands who regularly quote dialogue from The Godfather. This is not always ideal, particularly if you don't enjoy other forms of cardiovascular exercise, like masturbation. Some people, hoping to find a happy medium, instead imagine themselves making love to Robert Deniro, or a young Marlon Brando, depending on the scene. Few people enjoy sleeping with Luca Brasi, as this accounted for half of all new chastity converts in 2002.
