Look At Sick People To Give Your Immune System a Boost

Scientists at the University of British Columbia have found that looking at someone who appears sick boosts your immune system. Subjects had blood taken before and after watching a 10-minute slide show that contained disturbing images including people who appeared sick. Results of the blood tests showed people who had seen the sick people had a stronger immune system. From the article: "In the study, young adults were asked to watch a 10-minute slide show containing a series of unpleasant photographs. Some pictures included people who looked obviously ill in some way. The subjects' blood samples were then tested for levels of interleukin-6 (IL-6), a substance produced by the immune system that indicates your immune system is ramping up to more aggressively fight infection. As a control, pictures of people brandishing guns were also used on some participants—and they barely resulted in a significant increase in IL-6 production, signifying that IL-6 production is not simply a reaction to stress."

Makes good sense

This makes perfect evolutionary sense for an emergent, highly social species. Without such a mechanism, it is possible that cities could never have occurred.

Better talk about it the other way around, or some people might strenghten their weird understanding of evolution.

When our ancestors were encountering visibly sick individuals, those with traits of discovered mechanism were somewhat more likely to survive and leave offspring.

Correlation Is Not Causation

[shambalagoon]

I just noticed the "correlationisnotcausation" tag. Is that just a knee-jerk reaction to studies now?

Are we suggesting that an increase in immune system activity CAUSED people to view a slide show about sick people?

Not really

A gun is just a tool. The purpose relates to the intent of the person with the gun.

My intent with my Glock, and therefore the purpose is self defense from criminals, and wild animals. If you have to go to south Phoenix with a lot of cash, or happen to be walking your dog and happen upon a herd of Javilina in the spring, you'll see what I mean.

My intent with my rifle, and therefore the purpose is recreation. It's fun and challenging to shoot targets 100s of yards away with iron sights.

My father's intent with his rifle is to shoot, and subsequently eat a deer, therefore the purpose is hunting.

A criminal's intent bay be to kill a competitor or rob a store, therefore the purpose is to kill or at least threaten people.

Tools do not have intent; they are inert. It takes a person to bring intent and purpose to the tool.
