Jack Smith On Biohacking, 2 Easy Business Ideas, PLUS Why Procrastination Is Good

Jack Smith is a serial entrepreneur (Vungle, among others) who has thought carefully about what is actually worth doing with your time and capital. His opening move in this episode is to separate the 1% of biohacking that is evidence-based and high-leverage from the 99% that is expensive theater. His short list: sleep, zone 2 cardio, strength training, and protein intake. Everything else—the ice baths, the peptides, the expensive supplements—is mostly noise with marginal effect sizes. He is not dismissive; he just applies the same returns analysis to health that he applies to business.

The mobile DEXA scan business idea is the most concrete thing in the episode: DEXA scans measure body composition precisely, cost roughly $100 per scan, and most people have to drive to a specialized clinic to get one. A van-based mobile DEXA service—booking through Instagram or a simple website, operating in wealthy suburban zip codes—is a high-margin, appointment-only service business with almost no capital requirements beyond the equipment. Smith estimates the unit economics work at a low volume of scans per day.

Medical tourism brokerage is the second business idea: a concierge service that identifies the best facilities in Mexico, Thailand, and Eastern Europe for specific elective procedures, handles logistics, and charges a percentage of the cost savings. The actual value is curation and trust, not logistics—patients don't know which Tijuana clinic is excellent and which is dangerous, and a trusted intermediary solves this.

The procrastination thesis is the episode's counterintuitive anchor: Smith argues that smart people often procrastinate because they intuitively sense a decision is premature. Rather than treat procrastination as a character flaw, he suggests asking whether the delay is protecting you from a bad move. Anti-beast-mode: the best operators don't grind through uncertainty; they wait for clarity.
