“One of the things you will find, which is interesting and people don’t think of it enough, with most businesses and with most individuals, life tends to snap you at your weakest link. So it isn’t the strongest link you’re looking for among the individuals in the room. It isn’t even the average strength of the chain. It’s the weakest link that causes the problem.” – Warren Buffett

“All the frontier labs are speeding up their own developers using AI tools, but it’s not very neat. It seems to have the property of “you’re only as fast as the weakest link in the chain”—for instance, if you can now produce 10x more code but your code review tools have only improved by 2x, you aren’t seeing a massive speedup.” – Jack Clark, co-founder of Anthropic (20260110)

Jerzy Gregorek says it’s usually one organ that causes all the others to fail.

And he relates this to joints. Your weightlifting performance (e.g., squat) can improve a lot, for example, by addressing the mobility of ankles—just by few degrees.

Fix your weakest link.

Interesting Research:

  • Dr. Winsor’s autopsies (a series of studies conducted by Dr. Henry Winsor in the 1920s)
    • Rather than disproving chiropractic theory, it ended up reinforcing the idea that there is a connection between spinal health and overall body function, including organ health. His findings suggest that degeneration in the spine can correspond to degeneration in organs controlled by nerves at the same spinal level, highlighting the importance of spinal alignment in maintaining good health.
