Bryan Johnson — billionaire, tech entrepreneur, and self-styled biohacker — has been waging a very public war against aging.
He’s spent millions measuring, tracking, and optimizing every inch of his body, calling himself “the most measured human in history.” His stated goal: to live forever. He’s 49.
Recently he even posted his birth details on X, inviting anyone to predict the date of his death.
It’s considered taboo in astrology to forecast death. But I couldn’t resist taking a look at his chart.
What the chart shows:
- 1st house: Strong and unafflicted — good overall vitality
- 12th lord in 8th house, at the last degree: Weak placement related to loss and longevity
- Saturn, the karaka of longevity: Average strength
- Mars, the D8 ascendant lord and special longevity significator: Also weak in the 8th house, under 1 degree
Verdict: Medium lifespan. The chart suggests 36 to 72 years. Living into his 80s or beyond looks unlikely based on these placements.
