Lyrics:
Verse 1
Tiny sparks in the blood, in the bone, in the brain
Not the headline calories, but the quiet things we crave
On bright screens we chase the patterns in the haze
Old choices in the code, still calling out our names
Pre-Chorus
Not one switch, not one lucky break
It’s a handful of wires the body learned to take
From salt and stone and dust, we changed our fate
Now the past is in the pulse—listen when it shakes
Chorus
We were built in the trace, in the micro and the minute
Carried by the drift, then the pressure got in it
Not one gene crown, it’s a crew that keeps it spinning
If the ground runs thin, we feel it—so we stay in it
Verse 2
Some places held the iodine like a hidden fire
Some chased selenium in a razor-thin wire
Zinc on the move, through the gates and the lines
Transporters and the dials, turning need into design
Bridge
Before the fields, before the plow, the signal was alive
Standing in the variation, waiting to arrive
But today the soil’s tired and the margins get tight
So measure what you’re missing in the middle of the night
Final Chorus
We were built in the trace, in the micro and the minute
Oligo in the answer—more than one to win it
If the map’s not complete, we still read what’s written
Watch the ground, watch the blood—keep the future in it
