Once my shoe starts to go, I'll start to get intense pain in my hips and knees. Changes the shoe, and the pain goes away. It's a form issue in my case which the shoe helps to correct. I'm guessing those people who run barefoot have really good form.

I don't know how old you are, but it might be a matter of age for some people. My father-in-law, a 62 year-old former police officer, has been running every day since he joined the police academy and still runs several miles a day up and down the mountainous roads near his flat.

I mentioned Nike Free to him when those first came out and he laughed and said he would be in agony if he ran without the support that his shoes offer him. Maybe it would have worked when he was younger, but it definitely won't now. For now he says just stick with $10 running shoes from Michaels that he has to replace every month!

And he once was convinced he found a security breach in my code because he composed a GET request, making a pistol gesture and a "pow" sound.

Being able to compose an HTTP GET request just by making a pistol gesture and a "pow" sound definitely requires some serious "skillz." No matter how much I tried, I couldn't replicate this on my PC. I tried every conceivable pistol gesture and permutation of "pow," "ka-blooey," "Muad-dib," etc. It wasn't happening for me.

In the language of the eligibility requirements for the DTV coupons, it has language that strictly limits the feature set of the DTV tuner boxes. I believe there aren't any hidden features put in by manufacturers for fear of running afoul of the rules and being disqualified from being eligible for the coupons. Of course, risking disqualification from the program means significant revenue impact.
