TO: All Alternate, Adjacent, Divergent, Abandoned, and Otherwise Plausible Versions of Z
FROM: The Committee
DELIVERY METHOD: The Ether, the Multiverse, and Substack
RE: Your Continued Participation in This Timeline
Dear Other Zs,
Following yesterday’s Substack, Training for the Bounce: Training for Future Me, the Committee convened to discuss implications. This is rarely advisable, but by the time anyone recognized the danger, quantum immortality had already been introduced into the conversation.
For the record, the Committee does not believe quantum immortality is established reality. We are not physicists. We have no experimental evidence suggesting that consciousness somehow continues only along the branches in which we survive. Frankly, we barely understand what a wave function is, and several members continue to use the phrase “quantum” whenever they want something to sound more interesting. Nevertheless, as a thought experiment, the idea has proven annoyingly difficult to put down.
If reality branches into countless possible versions of us, then somewhere there presumably exists a Z who made every slightly different choice available this morning. One went to the gym. One stayed in bed. One decided he had been doing pretty well lately and deserved a break. One celebrated losing fifty pounds by gradually returning to every behavior responsible for needing to lose fifty pounds in the first place. Another Z intends to begin lifting seriously next week. Several are apparently waiting for Monday, which remains the most heavily populated starting date in the known multiverse. The Committee has reviewed these possibilities and would like to clarify our position: we intend to be the Z who continues. This is not a threat. It is more of a notice. Possibly a hostile takeover.
Yesterday’s essay shifted something for us. Health is no longer primarily about weighing less, looking better, or attempting to delay the indignities of getting older. We are preparing for Future Z. Somewhere ahead is an older version of us who will eventually get knocked down by something. We do not know what it will be or when it will happen. We do not get to negotiate those terms. What we can influence is the body he occupies when it arrives.
So we are building one for him now. We are adding muscle, mobility, balance, cardiovascular capacity and endurance. We are carrying less unnecessary weight. More importantly, we are developing the extremely unglamorous ability to keep doing something after it stops being exciting. This may prove to be the most useful adaptation of all.
And this is where quantum immortality becomes fun. Not because we expect our consciousness to magically leap from a deceased Z into whichever neighboring Z still has a pulse. That seems both scientifically questionable and administratively exhausting. The Committee cannot imagine the forms involved. But as a metaphor, it works beautifully. Every decision opens some trajectories and makes others less likely. Somewhere there is a Z who gets stronger. Somewhere there is one who slowly gives up capacity. One keeps exploring. One gets comfortable. One keeps making small deposits into a future he cannot yet see. Another keeps borrowing from that same future under very favorable terms for Present Z.
We have decided to discontinue that lending program. Future Z now has representation on the Committee, and his voting record is extremely predictable. He would like us to walk. He would like us to lift weights. He would prefer that we drink some water. He has issued several strongly worded opinions regarding sleep. He is also apparently very invested in us maintaining enough leg strength to get off a toilet without turning the event into a team-building exercise. We consider his concerns valid.
There is also some good news. Becoming the healthiest version of ourselves by fifty does not require overcoming a legendary athletic peak from our twenties. Twenty-year-old Z weighed close to four hundred pounds, so in a rare act of strategic foresight, he established an extremely approachable benchmark. Thank you, Young Z. Your contribution has been noted. Still, this is no longer really about surpassing him. It is about building something we have never had before. We are not trying to recover a younger body. We are trying to create a stronger older one.
So to the rest of you Zs scattered across hypothetical reality, the Committee would like to offer some guidance. Go for the walk. Lift the thing. Drink the water. Eat something that at least vaguely resembles the form in which nature produced it. Go to bed. Then do some version of those things again tomorrow. You do not need to become heroic. In fact, heroism seems suspiciously unsustainable. You simply need to stop defecting from Future You in tiny increments.
Because that is probably how most versions are lost. Not through one enormous, cinematic decision in which a man announces that he has chosen decline. Nobody wakes up, stares meaningfully into the bathroom mirror and declares, “Today I begin the irreversible erosion of my physical capacity.” It happens through negotiations: skip today, start Monday, you’re tired, you’ve earned it, you’re doing better than most people anyway, one week won’t matter, Future Z can handle it. For decades, Future Z has had terrible legal representation. That ends now.
We imagine him somewhere in his seventies. Maybe he still travels. Maybe he chases grandchildren around. Maybe civilization has collapsed and he spends his mornings tending a rooftop vegetable garden while an AI-managed raccoon militia patrols the neighborhood. The details remain unclear. But eventually something happens. The hiccup arrives: a fall, an illness, a surgery, some ordinary betrayal by biology. And when that happens, we want him to have resources. We want muscle left in the account. We want balance, lungs, heart, movement and stubbornness. We want the event to be something that happened to him rather than the moment his world permanently became smaller. That is the branch we are trying to construct.
Which brings us back to you, Other Zs. You remain free to make your own choices. Presumably that is why reality bothered generating you. But once the Committee allowed quantum immortality into the meeting, following the thought experiment to its natural conclusion became unavoidable: we intend to absorb your timelines. Metaphorically. Probably. The Zs who keep moving will continue downstream. The Zs who stop may discover that entropy has an absolutely flawless attendance record.
Accordingly, the Committee issues the following invitation: Follow or perish. Legal has requested that we again emphasize the metaphorical nature of this statement. Legal is no fun. But the sentiment remains. We are taking the branch where fifty is stronger than forty. We are taking the branch where seventy has options. We are taking the branch where getting knocked down remains an event rather than becoming an identity. We are taking the branch where the old man gets back up.
If you are another possible version of us somehow receiving this transmission through the quantum foam, please consider it your formal notice. You are welcome to join us at any time. There is no admission fee. No initiation ritual. No sacred oath. You just have to keep choosing the branch.
If you choose otherwise, we bear you no ill will. You are us, after all. Or you were. Or you might have been. We admit the metaphysics become slippery precisely where this letter requires them to be specific. Still, it has been an honor sharing the wave function with you.
We are leaving the light on at the gym.
Respectfully transmitted into the void,
The Committee
