Men: Wanna save $840 over 12 years?

Today, I read an article while I was procrastinating on my homework. The article is about how to drastically prolong the life of your razor. I know, personally, that Gillette razors and other disposables can cost about 30 dollars for one pack, that will only last you a few months. The article that I read explains that you should rub the razor up the pant leg of bluejeans 10 to 15 times and then down the leg 10 to 15 times. The direction of the razor should be so that you're NOT shaving the pants; you should not be trying to cut the jeans with the razor. By doing this, you are cleaning the razor, sharpening it with the ridges of the jeans, and also straightening out any bent parts of the razor. Supposedly, this tactic could save you 70 dollars per year and 840 dollars over 12 years! Just think of what you can do with all of that cash!
