Calculating Lifetime Reserve: Mortality Mathematics by Mark Hatmaker



[Originally offered as "Can You Afford the Time to Read This? Can You Afford Not To." By request, I offer these two pieces as a whole. Those who find this approach to life soul-resonating may find Part 3, "Lifetime Asymmetry" of like value.]

How old are you? Me? I’m 58, be 59 in 3 weeks.

Convert your age into months. Me? 696 months and 3 weeks.

The average lifespan of the adult male in the US is 74.8 years, for women it is 76.3.

That’s 897 months and 912 months respectively.

The average human lifespan is less than 1,000 months.

[And that’s assuming we make it that long. There Are NO Guarantees.]

If you are a male and are 38 years old or older, you have already used up over half of your average lifespan reserve.

39 or older if you are female.

Subtract your current lived months from your average lifespan months to get your lifespan reserve.

Me? That’s 201 months remaining.

You have slept for an approximate 1/3rd of your life.

You will continue to do so.

Subtract 1/3rd from your reserve.

For me that leaves 134 awake months in my lifespan reserve.

For most of us work, paying bills, trips to the store, traffic, scrolling your phone, downtime for flu, watching TV, etc. take up another approximate 1/3rd of our lives, so subtract an additional 1/3rd from your remaining reserve.

For me? Well, that drops it to 67 months.

67 months presumably free and clear to pursue aspirations, dreams, goals, hone skills, take up new hobbies, go on new adventures etc.

Keep in mind that 67 months is 5 ½ years.

That’s it.

Do your own calculation from months to years and see how much “free lifetime” is left to you.

And keep in mind these years at the latter half of life are statistically less mobile, less agile, less able as we all fight against the inevitability of entropy.

So, if we calculate it in “free lifetime” alone, me with my 5 ½ years and you with your own “End Date”, ask yourself…

·        Are you using these end times well?

·        Are you squeezing all the juice out of what ya got while ya can?

·        Drinking life to the dregs?

·        Catching all the sunrises, sunsets, moon-viewings, flower smellin’s, cat pettin’, dog hugging, loving and kissing that you can?

·        Or…

·        Are you running out the clock pretending that the Mathematics of Mortality do not apply to you?

I wish nothing but long healthy happy lives for all, but…we all know that is an impossibility in many cases, perhaps our own.

What we do have control over is the right here, the right now. And then the moment after that.

And then the next. It is these moments that make up our remaining months.

Fill them bright and pure, Brothers & Sisters!

Now, I know some of you will find this all dire as hell, others inspiring as hell.

Either way, the math is the math.

Embrace the facts and GO!

HOW TO DOUBLE YOUR LIFETIME RESERVE: Life Reserve Addendum

For those who were/are depressed by the Life Reserve Mathematics.

I offer that “Memento Mori” [“Remember you must die”] is a lop-sided equation.

It is the stick in a carrot-and-stick spur to betterment.

The carrot that is the obverse of memento mori, which is [to my mind] the more powerful and useful is “Memento vivere!” [“Remember you must live!”]

·        Do not let lifetime reserve daunt you.

·        Use the mathematics to say, “Oh, I better get on the stick!”

·        Ask of everything, “Is binge watching Karate Kid the best use of my life?”

·        “Is this meme-sharing, fist-shaking, phone-scrollin’, traffic fuming getting me to Happy with a capital H?”

·        Memento vivere! Asks us to Wake Up to the Facts of Mortality.

·        Sniff each moment for the gift it is.

·        Those who can grasp that “Be. Here. Now. Appreciate. The. Now.” Double their Lifetime Reserve.

How is that possible?

The 1/3rd of life that is not free time the 3rd devoted to work, traffic, trips to the store can become additional moments of “Live in the Moment.”



When the Missus was facing down the barrel of the brain tumor gun, we sat in traffic on stormy rainy winter days headed for Vanderbilt Hospital for more treatment. The worry always lay hard in the pit of the stomach, yet I would look over at her and she at me and this traffic was yet one more moment she was right here—alive and I was right there with her.

If I didn’t have her, I would kick and scream and cry for those moments in traffic, those times “stuck” in line at a store.

So, yes, memento mori, we will die—all of us—some of us sooner than the expected reserve. If not you, someone you love.

This is not a warning; it is an inevitability.

It is the fact of life, the fact of death.

But…

Memento vivere!

Grab it, squeeze it, hug it, use it NOW!

Your Freetime Lifetime Reserve + your 1/3rd Duty Time can double your Lifetime Reserve but…

Only if you use it. Only if you are alive and awake to it.

Only if you live honestly.

Let us allow the polymathic Johann Wolfgang von Goethe express why we should weight the other side of the equation.

“Memento mori! Enough of that,

I’d rather not repeat it;

In the flight of life, why should I

Torture you with its limits?

Therefore, like an old curmudgeon,

I recommend to you, docendo, [Teach by example]

My dear friend, in your own way,

Just memento vivere!"

Lifetime Mathematics requires balance in the equation.

Scare the hell outta yourself with memento mori, now get giddy as F with memento vivere!

All the best my Brothers & Sisters!

Now go Live and docendo to others by your glorious example!

Mabitsiar’u!

Apache Running by Mark Hatmaker

Of the many Native American tribes of the southwest United States and Mexico the various bands of Apache carry a reputation for fierceness, resourcefulness, and an almost superhuman stamina. The name “Apache” is perhaps a misnomer as it refers to several different tribes that are loosely and collectively referred to as Apache, which is actually a variant of a Zuni word Apachu that this pueblo tribe applied to the collective bands. Apachu in Zuni translates roughly to “enemy” which is a telling detail that shines a light on the warrior nature of these collective tribes.             Among the various Apache tribes you will find the Kiowa, Mescalero, Jicarilla, Chiricahua (or “Cherry-Cows” as early Texas settlers called them), and the Lipan. These bands sustained themselves by conducting raids on the various settled pueblo tribes, Mexican villages, and the encroaching American settlers. These American settlers were often immigrants of all nationalities with a strong contingent of

The Empirical Fighter: Rules for the Serious Combatant by Mark Hatmaker

  Part 1: Gear Idealized or World Ready? 1/A: Specificity of Fitness/Preparation If you’ve been in the training game for any length of time likely you have witnessed or been the subject of the following realization. You’ve trained HARD for the past 90 days, say, put in sprint work and have worked up to your fastest 5K. Your handy-dandy App says your VO2 Max is looking shipshape. You go to the lake, beach, local swimmin’ hole with your buddies and one says “ Race you to the other side!” You, with your newfound fleet-of-foot promotion to Captain Cardio, say, “ Hell, yeah!” You hit the river and cut that water like Buster Crabbe in “ Tarzan the Fearless ” with your overhand stroke….for the first 50 yards, then this thought hits as the lungs begin to gasp for air, “ Am a I gonna die in the middle of this river?” This experiment can be repeated across many domains of physical endeavor. ·         The man with the newfound Personal Record in the Bench Press getting smoked in

The Original Roadwork by Mark Hatmaker

  Mr. Muldoon Roadwork. That word, to the combat athlete, conjures images of pre-dawn runs, breath fogging the morning air and, to many, a drudgery that must be endured. Boxers, wrestlers, kickboxers the world over use roadwork as a wind builder, a leg conditioner, and a grit tester. The great Joe Frazier observed… “ You can map out a fight plan or a life plan, but when the action starts, it may not go the way you planned, and you're down to the reflexes you developed in training. That's where roadwork shows - the training you did in the dark of the mornin' will show when you're under the bright lights .” Roadwork has been used as a tool since man began pitting himself against others of his species in organized combat. But…today’s question . Has it always been the sweat-soaked old school gray sweat suit pounding out miles on dark roads or, was it something subtler, and, remarkably slower? And if it was, why did we transition to what, and I repeat myself,
