Jack LaLanne died at 96 years old, yet my grandpa who's eaten tons of Taco Bell for most of his life is alive at just a hair from that age. I wonder what people will think about the obsession with "longevity" in the likely outcome of David Sinclair or Andrew Huberman dying in their 80s or earlier.
There a tribe in Ecuador with reduced height studied by Walter Longo etc. They have a mutation in their growth hormone receptor, that means that they experience less effect of human growth hormone, hence reduced height. And their lifestyle is rather unhealthy: alcohol, smoking, sugars, junk food, obesity etc. Yet they rarely experience diabetes, cancer etc probably due to reduced mTOR pathway activation.
In the context of this specific post regarding Charlie Munger, you can't say that it's genetics unless you measure specific genes. He could be 100x Bryan Johnson, but Bryan Johnson at least makes his protocols open for use. And Munger didn't even bother to make a genetics test with his curiosity, thus providing no essential value to human civilization.
