Bryan Johnson tracks his nightly erection duration as a biomarker of aging. He currently averages 2 hours 12 minutes, which he says indicates a biological age of 49, and aims for 3 hours 30 minutes to reach an age-18 marker. He's measuring penile blood flow and other baseline metrics to guide rejuvenation therapies.
I did my nighttime erections and I averaged 2 hours and 12 minutes per night in erections, which is a biological age of about 49, so three years older than my chronological age. I need to see if I can do some therapies to reduce the biological age. If I'm going To achieve age 18 of nighttime erections, I need to have three hours and 30 minutes. So I need to increase my nighttime erections by roughly an hour and 20 minutes on that marker blood flow min max urination speed and then penis plaque will also have these baseline measurements to know what therapies we need to do to rejuvenate the penis.
