All we really have to do to be healthy, fit, energetic, happy, productive, etc...is find those behaviors that promote gene expression (or turn it off in some cases) in the direction of health versus sickness. In most cases, this means emulating what our ancestors did prior to agriculture. It's really a simple list of rules, but it's very difficult for some people to grasp or to follow within the context of this complex, industrialized, information-glutted, hedonistic, instant gratification society.

A protein by the name of JNK comes to mind. With aging and insulin resistance, JNK is elevated and basically functions to shut off the insulin receptor --thus causing insulin resistance. Following exercise, insulin resistant populations show reduced JNK activation. The same protein in healthy young adults has increased activated after exercise, and greatly improved insulin sensitivity. Interestingly, if you compare older/insulin resistant JNK activation to that of younger healthy people, they end up with the same relative level of activation after exercise. Its just fascinating to me that the same protein can cause insulin resistance or actually reverse it depending on the population of interest.

I'll stop by to get my scrubs! We appreciate the nod. Thanks, Doc. I’ll stop by to get my scrubs! We appreciate the nod.

You get two things with this dubious honor: Recognition and hopefully some additional traffic from other medical blog readers who might not ordinarily visit your site, and a free pair of red scrubs. Yes, they're free and yes they are red!:) There is no catch. I am not trying to sell you anything...I promise. This is simply our way of recognizing and giving some sort of award to those who take the time to get involved in the medical blogging community. So, if you'd like your free scrubs, just send me your size and mailing info. by this coming Wednesday. Otherwise, the scrubs go to the first runner up on the honorable mention list. Congrats, Dr. Incognito Mark,
