CONCEPT — Our Philosophy

THE CONCEPT.当ラボの理念

Reboot Data Lab reframes the age-old theme of abstinence not as emotion or spiritualism, but as measurable data. Hormones, neurotransmitters, sleep, focus — we visualize the changes in the body and aim to establish a reproducible methodology for rebuilding oneself.

WHY ABSTINENCEなぜ禁欲か

Why we study abstinence.

In an age of constant overstimulation, the ability to control one's impulses is a key factor shaping physical and mental performance. We capture these changes scientifically from three perspectives.

01

PHYSIOLOGICALPhysiological Change

We keep daily self-recorded subjective and semi-objective measures, such as the libido index and EHS (nocturnal/morning erection hardness).

02

PSYCHOLOGICALPsychological Change

Focus, self-efficacy, impulse control. We record shifts in cognitive performance using standardized metrics.

03

BEHAVIORALBehavioral Change

Not temporary shifts, but lasting behavioral change. We pursue the science of consistency.

METHODOLOGY研究手法

Our methodology

STEP 01

Daily self-recording

Two subjects self-record 50+ items daily — libido index, EHS, sleep and others — following an identical procedure. No clinical blood testing is performed.

STEP 02

Normalization and visualization

Each measure is normalized to 0–100, combined by fixed weights, smoothed with an EMA, and visualized as trajectories. With n=2 we run no significance testing and stay descriptive.

STEP 03

Publication and DOI

We publish the recording procedure and data definitions, aiming to make the record third-party verifiable through a preprint and a dataset DOI.

Exclusive Dataset — 730 Person-Days

One year × two subjects × near-zero missing days.
A daily-resolution record of long-term abstinence.

To our knowledge, no publicly available dataset tracks abstinence daily, across multiple indicators, for 365 consecutive days with near-zero missing entries. Published here are 730 person-days of observation from two male subjects — one in his 30s, one in his 50s — in a physician-reviewed dataset (Ver 1.1). This is an n=2 self-tracking study, not generalizable medical evidence: we offer a detailed record of what happened, not a promise of what will happen to you. Within that honest scope, this data has a resolution found nowhere else.

365 days × 2 subjects, near-zero missing entries Physician-reviewed dataset Ver 1.1 Subjective × semi-objective dual-indicator protocol

Subjective Indicator — 主観指標

① Libido Index over 360 days: 30s vs 50s

Abstinence is not a straight climb. The two age cohorts traced nearly opposite paths — yet after one year, they arrived at almost the same place.

30代 / 30s 50代 / 50s Y = libido index (1–10) / X = days of abstinence

30s: early crash

10 → 3

0〜30日 / days 0–30

50s: mid-course bottom

240日 / day 240

Both: final convergence

10 / 9

360日 (30代/50代) / day 360

01

The myth of the straight climb

The core finding: abstinence does not rise linearly with time. Both records trace a nonlinear arc — crash, recovery, oscillation, then stabilization at a high level. The simple ever-upward story told on social media does not appear in either of these records.

02

Radically different by age

The 30s subject crashed from 10 to 3 in the first month, hovered near 6 for over half a year, then reached 9–10 late. The 50s subject surged to 8–9 by day 60, sank to 3 at day 240, recovered to 10 at day 300 and finished day 360 at 9. Same practice, opposite early responses.

03

Different paths — same destination

With both full-year records complete, one statement is now possible: two subjects on opposite trajectories both converged to 9–10 by day 360. Individual variation is not failure — it is a path. If you are in a valley right now, this is not consolation; it is data.

* Monthly measurements (Monthly Master). Both subjects: 365 days of daily records (near-zero missing). Values are single-day subjective ratings (1–10).

Semi-Objective Indicator — 半客観指標

② EHS (nocturnal/morning erection hardness) normalized score: 30s vs 50s

Mood and body do not always agree. Independently of the subjective libido index, we tracked a semi-objective bodily indicator for 365 days.

30代 / 30s 50代 / 50s Y = EHS normalized score (0–100) / X = days

30s: bottom

22

lowest, near day 60

50s: early peak

89

30〜60日 / days 30–60

Both: final convergence

93 / 87

360日 (30代/50代) / day 360

01

Why pair a bodily indicator

A subjective index alone invites the placebo critique. So we independently tracked EHS — nocturnal/morning erection hardness — as a semi-objective bodily indicator. Two channels of evidence, each auditing the other.

02

Mood and body diverge — then align

The 30s subject fell from 79 to 22 near day 60 — the same window as his libido crash — then recovered to 93 by day 360. The 50s subject peaked at 89 early, dipped, and climbed stepwise to 87. The two channels diverge in places and align at the deep valleys and the finish — that overlap pattern is itself information.

03

Internal consistency underwrites the data

Two independent indicators tracing the same valley (30s, near day 60) and the same high-level convergence at the finish means the change was recorded at the bodily level, not only in self-report. Where n=2 limits breadth, internal consistency and near-complete coverage supply depth — that is this dataset's design philosophy.

* EHS (Erection Hardness Score) is a 1–4 hardness rating; daily entries averaged in 30-day bins, normalized to 0–100. Both subjects: 365 days of daily records (near-zero missing). Not intended for medical diagnosis.

01

Locate yourself on the curve

Line charts show the flow; this table lets you place yourself in it. Find your age column at your current milestone and see where the two records stood. Note that this table shows the value on that single day. Charts ① and ② above use 30-day averages, so the numbers will not match for the same day.

02

Read the shading, skip the numbers

Cells darken with higher scores. The 30s subject's day 60 (libido 20, EHS 0) stands out as nearly blank — deep valleys happen even at milestones. And in both records, valleys were waypoints, not endpoints.

03

Mood-body coupling, one row at a time

With libido (subjective) and EHS (bodily) side by side in each row, coupling is instantly visible: both crash for the 30s subject at day 60, both max out for the 50s subject at day 300, all four finish high at day 360. Paired channels earn more trust than self-report alone.

* Libido = SimpleIndex; EHS = normalized morning-erection hardness. Both normalized to 0–100 and capped at 100 (correcting normalization outliers). Data: physician-reviewed Ver 1.1; both subjects, 365 days of daily records (near-zero missing). Values are single-day measurements at each milestone and do not reflect surrounding daily variance. Not intended for medical diagnosis or advice.

PROTOCOL — Recording Protocol

THE
PROTOCOL.365日間の記録手順

This is how our two subjects kept a daily record for 365 days under a single procedure. The study began as a 90-day plan and was extended in stages to 365 days. It is not an intervention program; it is a disclosure of how the records were kept and what they showed.

DESIGN HISTORY経緯

A 90-day plan, extended in stages to 365 days.

The record began as a 90-day plan. At day 90 — the planned endpoint — interest in the subsequent course had grown, and the next step was set: an extension to 180 days (six months). At day 180, for the same reason, the record was extended again to 365 days.

Neither extension was pre-planned; each was decided after the record up to that point had been kept. The procedure, including the recorded items and rating scales, was not changed at either extension.

As a result, phases that neither a 90-day nor a 180-day plan could have captured appeared in the second half of the record.

WHAT 90 OR 180 DAYS WOULD HAVE MISSED途中で止めていたら

Wherever the record had stopped, it would have stopped mid-course.

01

At day 90 and at day 180, values were still in the mid range

The libido index was 6 for both subjects at day 90, and 6 and 7 at day 180. EHS (30-day average) was 46 and 41 at day 90, and 42 and 48 at day 180. The day-360 values were 10 / 9 and 93 / 87.

02

The 50s subject's deepest valley came at day 240

His libido index fell to 3 at day 240 and returned to 10 by day 300. Both lie beyond the 90-day plan — and beyond the 180-day plan as well.

03

The 30s subject reached high values only after day 300

After a low near day 60, he stayed in the mid range (6–7) through day 270, then rose 8 → 9 → 10 from day 300 — also beyond the 180-day plan.

Monthly measured values from the DATA LAB page. Individual records from n=2; not generalizable effects.

01
ONBOARDING — 導入期

Initial Reset

This is the period for starting the record and establishing a baseline; it is where the subjects built the daily habit. From day 31 on, the procedure is simply to keep doing the same thing.

DAY 1 — 30
WHAT WAS RECORDED記録項目の内訳

Daily numeric records, plus fixed-point photography.

The records our two subjects kept over 365 days are not limited to numbers. Numeric logging formed the backbone, and fixed-point photography was used alongside it as a supporting record. Below is the breakdown of what was actually recorded.

PRIMARY主軸

Daily numeric logs

Libido index, EHS (nocturnal/morning erection hardness), morning erection duration, sleep, body composition and 50+ other items, logged daily by an identical procedure. These numeric records are what the lab publishes and analyzes.

SUPPORTING補助

Fixed-point photos (face / body)

Weekly, with camera position, lighting and time of day held as constant as practicable, the face and body outline were photographed and archived. These are internal records kept to support the numeric logs; they are not published or analyzed.

SCOPE取り扱いの範囲

Because a photograph's appearance shifts with shooting distance, angle and lighting, the lab does not treat photographs as evidence of effect. Assessment of change is based on numeric records measured under fixed conditions. The fixed-point photographs are part of the recording procedure only, and there is no plan to publish them on this site.

OBSERVED PHASES観察された局面(事後記述)

The phases were outcomes, not steps.

These divisions were drawn after the fact from the records; they are not part of the procedure. The order and timing differed by age, and no single division fit both subjects.

30代 / 30s
  • Days 0–60: sharp drop (libido 10→3, EHS 79→22)
  • Days 90–270: mid range (libido 6–7)
  • Days 300–360: rise (libido 8→10)
50代 / 50s
  • Days 0–60: early rise (libido 4→9, EHS 89)
  • Days 90–240: fluctuation, then the deepest valley at day 240 (libido 3)
  • Days 300–360: recovery (libido 10→9)

The full trajectories of the measured data are always available on the DATA LAB page.

BY AGE BAND年代別の傾向

What each of the two records showed.

Under the same practice, the 30s and 50s records differed sharply in when the valleys came and how recovery unfolded. What follows are features of one person's record in each case, not tendencies of an age group.

30代(被験者1)30s (Subject 1)

An early crash, then a long middle stretch

Observed pattern: Within 30 days of starting, the libido index fell from 10 to 3, and EHS reached its low (22) near day 60. It then stayed in the mid range through day 270 and rose from day 300.

What the record suggests: In the record, having anticipated this valley as something that would come marked the difference for continuing. For reference, the subject paired this period with exercise and absorbing work.

50代(被験者2)50s (Subject 2)

An early lift, then a deep mid-course valley

Observed pattern: Early on (days 30–60), the libido index rose from 4 to 8–9, and EHS peaked at 89. It then fluctuated in the mid range, and the libido index fell to 3 at day 240.

What the record suggests: In the record, the mid-course valley was a waypoint, not an endpoint. The libido index returned to 10 at day 300 and stayed between 8 and 10 thereafter. Decisions involving your health should be made in consultation with a professional.

Record yourself with the same procedure.

The recording template and full procedure will be published for members once ready.

ABOUT — Who We Are

ABOUT RDL.当ラボについて

Reboot Data Lab is an independent research project that records changes in men's minds and bodies as measurable data. We publish 365 days of self-recorded data from two subjects as primary data.

OUR VALUES当ラボの価値観

Three values we hold dear

01

Scientific Integrity

We set aside emotion and assumption, conducting research based on measurable data and reproducible methods. We respect facts rather than convenient conclusions.

02

Respect for the Individual

Everyone changes at their own pace. Rather than forcing a one-size-fits-all answer, we publish material each person can judge from their own record.

03

Open Knowledge

We return our findings to the community and share them worldwide. Knowledge is to be shared, not monopolized.

OUR STORY

Data records
the change.

"Does abstinence really work?" — we wanted to answer that question with science. In 2025, that conviction led us to found this research project.

Our subjects today number just two — one in his 30s, one in his 50s. Yet completing over 360 days of near-gap-free daily records is exceptionally rare worldwide. From this honest record, we are advancing research on masculinity one step at a time.
