Engaging Your Survival Circuitry

Everyone who's approaching or past middle age wants to look and feel younger.
Nothing wrong with that. Nothing at all.
To accomplish such a thing, though, will require CONSIDERABLE work. In today's post, I'm going to look at three such work items: Three activities that, when done regularly, engage your survival circuitry and force your cells (and that which generates them) to behave (think and respond) younger so they can accommodate more effectively the mind-body stresses being placed upon them. These three things increase the production of NAD+ in your body, which the mitochondria in your cells use to energize your cells. Want to look and feel younger? Do that which energizes your cells.
Three Things that Activate Your survival Circuitry
1. HIIT (High Intensity Interval Training) Exercise.
Also called Sprint Interval Training (SIT), HIIT is a form of physical training that alternates short periods of intense anaerobic exercise with less intense recovery periods. The exercises are typically performed until you're too exhausted to continue. Interspersing Burpees with jumping jacks or jump rope, and running 50-yard wind sprints and then walking back to the starting line are two examples of HIIT. Training in HIIT taps into your primal drive to escape being attacked by a grizzly or saber-toothed tiger. The unconscious parts of you don't know you're training; they just know you're behaving as though you're trying to escape a predator. In "assuming" this, your survival circuitry kicks in, pretty much red hot.
2. Intermittent Fasting.
Intermittent fasting is a practice of eating, where you limit your feeding a 6- to 8-hr window each day (or each day you fast). For example, my daily feeding window is 12p-6p. During this window, I eat two, normal-sized (and nearly 99% plant-based) meals. Fasting in such a way creates an undercurrent of hunger, which forces my body to burn other sources of body fuel, such as fat stores and (through autophagy) malformed (e.g., cancerous) cells.
3. Cold exposure.
Cold exposure (especially, taking a coatless walk in the freezing cold, taking cold showers, or immersing yourself in freezing-cold water) forces your body to respond as if you fell in a raging river in the middle of winter.
Want to look and feel younger, practice one or more (or all three) of the above. It will change your life. Literally. I write of this from personal experience as I've been engaging in these practices every day for many years. Chronologically, I'm 54 years old. Biologically, I'm closer to about 33 years old.
