Pemmican The Ultimate Survival Food



The next survival crisis, which we may face soon, will be nothing more than what our ancestors called daily life.

The grid could go down and then we would have no electrical power, no refrigerators, no Internet, no computers, no TV, no hyperactive law enforcement, and no Publix or Walmart.

When the grocery stores close down, and the food shelves go empty, food will become a serious issue for most people.

Except for those who know how to make pemmican!

Pemmican was created by the natives of North America, and was used by Indian scouts, as well as early western explorers.

These people were highly mobile, and covered a lot of distance. They needed food that was nutritious and would not spoil.

Pemmican answered the call. You can store it for a long time without refrigeration. And it can be packaged in any way that you need, so that it can be carried easily during movement.

Learning how to make pemmican is just one of the many survival techniques used by our forefathers.

These precious life saving techniques are becoming lost to time.

When things go bad in today's world, we will all become frontiersman and pioneers again.

And we will need to learn the same skills that our grandfathers, and great grandfathers knew before us.

Click this link and watch this super informative video on how to make pemmican.

Start learning the skills that you, and your family, will depend upon during the next dark times.

We all have much to learn from our ancestors.

Pemmican is a great place to start.

And if you want to learn more about old school frontier and pioneer survival techniques, check out this great book:

Metabolic Energy Pathways and Your Fitness Training



     There are three metabolic energy pathways used by the body to produce energy to support physical activity. Each energy pathway stores, utilizes, and resynthesizes ATP in different ways. The three energy pathways are the phosphagen, glycolysis, and oxidative systems. The phosphagen, and glycolysis systems are anaerobic, and do not use oxygen. The oxidative system is aerobic, and does use oxygen. Each energy pathway is specifically used for a certain type of activity, and for a certain duration of time. All three energy pathways work in concert throughout physical events to ensure the body’s energy demands are met. Normally, no one single pathway provides all of the energy requirements during physical activity (Haff & Triplett, 2016).

     The phosphagen system process occurs in the sarcoplasm. It is utilized by activities that require a maximal output of strength and power, for a very short duration, typically in the 0-6 second range. Powerlifting, and Olympic weightlifting are two examples of sports, which utilize the phosphagen system Adenosine triphosphate (ATP) is the body’s main source of energy. It is utilized for basic cellular functions, as well as for all movement, and muscular actions. The body cannot store large amounts of ATP. There is approximately 80-100 grams of ATP stored at any given time (Haff & Triplett, 2016).

     With the phosphagen system, ATP has to be resynthesized rapidly, in order to meet the body’s energy demands. When ATP is utilized, it is broken back down into adenosine diphosphate (ADP) and creatine phosphate (CP). The ADP and CP are then synthesized back into ATP, with the help of the enzyme, creatine kinase. This creatine kinase reaction quickly replenishes the ATP stores. The phosphagen system has the fastest rate of ATP production, and the least capacity for ATP production, of the three energy pathways (Haff & Triplett, 2016).

     When the physical activity moves into the 6-30 seconds window, a combination of both the phosphagen and glycolysis systems are utilized. This combination is used for high intensity activities requiring high energy output. An example of a sport utilizing this combination would be track and field, with a variety of short distance sprinting, relays, and hurdles. At approximately the 30 second mark, the glycolysis system takes over until the 2 minute mark. The glycolysis system process also occurs in the sarcoplasm (Franchini, Takito, & Kiss, 2016).

     The glycolysis system is slower than the phosphagen system, but has a much larger capacity for ATP production. It involves the breakdown of carbohydrates from muscle glycogen, and glucose found in the blood. This breakdown of carbohydrates is ultimately used to resynthesize ATP. Glycolysis using blood glucose produces two ATP molecules. The glycolysis process using muscle glycogen produces three ATP molecules. The glycolysis system is complex, and uses two main routing methods or pathways (Franchini et al., 2016).

     These are referred to as fast or anaerobic, and slow or aerobic glycolysis. The end result of glycolysis is the production of pyruvate. The fast glycolysis pathway changes pyruvate into lactate, in the sarcoplasm. This causes the ATP resynthesis to happen much faster, but for a shorter period of time. A secondary lesser used route, for faster ATP resynthesis, uses the Cori cycle. Lactate can be moved through the blood to the liver, and then it is changed into glucose. The Cori cycle helps to get more glucose back into the glycolysis process, when blood lactate levels are rising (Haff & Triplett, 2016).

     Slow or aerobic glycolysis involves transporting the pyruvate into the mitochondria. The pyruvate enters the Krebs cycle, in order to resynthesize ATP. When this route is utilized, the ATP resynthesis rate takes longer, but it can go on for a longer period of time. Which process is used by the body depends on the energy requirements at that time. When ATP is needed quickly, the fast glycolysis is used. When the exercise intensity is a little lower, the slow glycolysis can be used for a longer period of time (Sousa, Vasque, & Gobatto, 2017).



     During the 2-3 minutes window, during activities of a moderate intensity, a combination of the glycolytic and oxidative systems is utilized to produce ATP. Short distance running would be an example of an activity, which would utilize this combination (Sousa et al., 2017).

     Once the activity passes 3 minutes, the oxidative or aerobic system takes over. The oxidative system then becomes the primary source of ATP production. The oxidative system is primarily utilized during periods of rest, and during low intensity activities, of longer duration. It utilizes fats and carbohydrates as its main substrates. Protein is not a major contributor to total energy. But it is used in greater quantities during aerobic events which last 90 minutes or longer. The oxidative system breaks down the three macronutrients, or substrates, into acetyl-CoA. The acetyl-CoA then enters the Krebs cycle to produce ATP. The oxidative system, starts with glycolysis, and also uses the Krebs cycle, and the electron transport chain (Sousa et al., 2017).

     The breakdown of one molecule of blood glucose results in the production of approximately 38 ATP molecules. If the glycolysis uses muscle glycogen, the count rises to 39 ATP molecules. Fat provides large amounts of ATP. The breakdown of a single triglyceride molecule can produce over 300 ATP molecules. This provides more energy for the long, steady state aerobic events. Marathons and triathlons are examples of sports, which utilize the oxidative system (Sousa et al., 2017).

     To maximize athletic performance, training should be based around the sport requirements and the supporting energy pathway. Some athletes need to spend time training in all 3 energy pathways, while others should focus only on the anaerobic pathways. For example, combat sport athletes need to train in each energy pathway singularly, and progressively. These athletes spend different amounts of time in each energy pathway window, and collectively move through all three during a competitive bout. Specific training that is tied to energy pathways, will allow the athlete to perform at optimal levels throughout their competition event (Martins et al., 2018).

Losing a Glove in the Winter Patrol Course


I bitch about the cold a lot. This we know. 

Today, I walked up my driveway to check the mail. 

It's only 28 degrees out and the icy wind is blowing.

My hands, feet, and face are affected by the cold right off, due to numerous minor cold weather injuries sustained over the years. 

The hands turned to ice in the short walk. I cursed myself for not wearing my gloves. 

Why do my hands freeze up so fast? 
Ah yes then I remembered.

During one of my winters in Germany, I had the privilege to attend the Winter Patrol Course, at the International Long Range Reconnaissance Patrol School (ILRRPS). 

Not another ILRRPS story? Yes, comrades! This is for my non-military friends who do not understand that a bitching soldier is a happy soldier.

So no shit, there I was (mandatory military story intro), on a high ridge line, in the mountains of southern Bavaria. 

I was on a 4 man LRRP team, conducting a graded patrol, during the final field training exercise. 

Because I was the only Yank (American), they stuck me as the RTO, with the radio, during the ascent up the mountain. 

At one of the higher points on the ridge line, we stopped to do a scheduled radio check in. 

It was cold and windy. Like really cold and windy!

I had to take a glove off to manipulate the radio dials. 

A strong gust of wind blew my glove clear off the mountain and dropped it hundreds of feet below.

It was at this point in time that I was eternally screwed. 

I pulled out my heavy wool socks and stuck my now frozen hand into them. It could not replace the missing gortex glove.

So I traded off the remaining gortex glove and wool socks, back and forth between both hands, for the remainder of the mission.

It didn't help, and my hands were forever screwed. 

My feet and face suffered a similar fate from being underdressed, outside in the cold, during various cold weather training events. 

They (VA) called it chilblain and frost nip. They said it was no big deal and wasn't service connected. So I got a goose egg in the disability rating.  

So whenever it gets cold and the wind blows, it kicks my ass.

My comrades understand what it means to lay in a snow bank all night, to have your feet so cold that you can't feel them at all, to have the water in your canteen freeze, to shiver so violently that you struggle to put a piece of food in your mouth, ( if you had food), to have your hands so cold that you can't move your fingers, to have your lungs and chest burn from breathing the freezing air, to be so cold that you pace back and forth all night instead of sleeping, and to limp around in intense pain after you thaw out.

So every time the temp drops even a few degrees, it hits me like a ton of bricks. 

That's why I went to Hawaii for four years, after my tour in Germany.  But that's another story.

Now I can stay warm, eat hot food, drink hot coffee and tea, wear all of the sweaters, hats and gloves, wrap up in blankets, and never experience that cold weather nightmare again. I'm thankful and grateful for that.

But even still, I freeze my ass off because of the old injuries.

So I don't bitch about the cold because I have it rough now.

I bitch about it because I'm still freezing from twenty years ago and it's painful. 

People who stay inside during cold weather, or only go out for a short time, have no clue as to what my fellow veterans and I have experienced.

When we talk about the cold, it's nothing that you can understand, unless you've spent a few nights (all night) outside in the snow, freezing. 

Have you ever staggered around a mountain ridge with hypothermia, hypoxia, chillblain and frost nip? No? 

The homeless dudes know what I'm talking about as they freeze their asses off outside right now.

I bitch about the cold sarcastically, not because of my suffering now, but because of the frozen nightmares I endured in my previous military life.

I don't have it hard now. The dudes that are still outside freezing have it rough. 

Stay warm you crazy kidz!
