Most men think the average erect penis is 6.2 inches.
It’s not. That data is self-reported.

The actual global average is 5.36 inches (13.61 cm), according to a 2020 meta-analysis of 10 studies.

Here’s how to collect your own penis size data, accurately.

Erection measuring protocol:

1. Ensure you are fully erect.

2. Place a rigid ruler on the top side of your shaft. Gently push it back until it touches the pubic bone (you may need to press through skin or hair).

3. Read the length where the tip meets the ruler.
Do not pull

@ConnerBean initially probably 5-7 hard core builders to figure out path

Have been interviewing CEOs and CTOs. They're surprised when I tell them the goal here is to build health with the same fever pitch intensity as seen in AI.

Ultimately it's the same thing.

@AMAZlNGNATURE but it's so pale!

My body screams at me after sitting for 45 minutes.

@ID_AA_Carmack I'd love to do this with my body

@BioProtocol we systematically plan out the tests weeks in advance and then determine best time and routine to ensure consistency of measurement

Your blood, stool, saliva, and urine reveal your life habits…

In the last 24 hours, I measured:

blood:
+ ADMA/SDMA
+ F2-isoprostane
+ Creatinine ratio
+ 8‑OHdG
+ Lipid peroxides
+ Antioxidant capacity
+ Omega‑3, omega‑6, omega‑9, saturated, trans fats
+ Delta‑6 desaturase

I measured the following things about my body during the past 24 hours. A typical day.

+ basal temperature upon waking
+ my brain @KernelCo Flow (wearable fMRI-like helmet)
+ morning RMSSD and SDNN
+ sleep performance via wearable and bed
+ exercise performance (2 devices)
