Here are a few links to articles and videos I found interesting this week. Some are intellectual. Some are informative. Some are just fun. If you have some free time, check them out this weekend.



Expiration Dates and Preparedness


In my medical classes I talk about how drug expirations work and about the military SLEP testing mentioned in this article.  The bottom line is that if your drug isn’t a liquid and doesn’t have a time release mechanism (extended release), it will likely remain at full potency for between two and six years AFTER the expiration date.

Jeff Gonzales shares some excellent advice about carrying and training with a folding knife.



Inspiring message of the day: obesity is not a disease and you do have free will


“I hear a lot about genetics, but people in the 19th century had genetics, didn’t they? Yet they didn’t have an obesity epidemic. You know what else they didn’t have back then? Cinnabon. Coincidence? Probably not.”

Beretta Accessories

eu00031Many gun companies won’t sell parts for their guns directly to the consumer.  I disagree with this practice.  I won’t carry a gun that I can’t fix myself.  And I can’t fix it if I can’t buy parts.  Beretta has now made parts available for their Model 92/M9 pistol directly on their website.  If you own one of these, pick up a new recoil spring.  If you do a lot of shooting, you probably need it.



Louis CK and the Hare Krishnas Used This ONE Trick for Success


Learn about the “law of reciprocity” and “commitment bias”. These are not limited to comedians. They are techniques that criminals and con artists will use as well. Being able to recognize when you are being manipulated is a critical skill to possess.



Center Mass in a Three-Dimensional World


“I’ll just shoot him in the legs.”

“Two to the chest, one to the head.”

“Double tap and done.”

“I’ll just shoot him in the pelvis and work my way up.”

All of these “plans” presuppose that your bad guy will let you.  We shoot to stop the threat and doing so means targeting the center of what is offered, or exercising discipline until you can maneuver for a clear shot or wait for the threat to give you one.  We should be wary of anything that always works on paper, just as we should probably be dubious of magic formulas that require a specific set of circumstances to work.  The only off switch is a hit (or more) to the central nervous system.  Outside of that, you can and should expect a threat to continue to fight regardless of where or how many times you hit them.  Until they lose consciousness or surrender, they are still a threat and should be treated as such by the continued use of controlled violence so long as you have a clear shot.”
