“Our normal waking consciousness, rational consciousness as we call it, is but one special type of consciousness, whilst all about it, parted from it by the filmiest of screens, there lie potential forms of consciousness entirely different. We may go through life without suspecting their existence; but apply the requisite stimulus and at a touch they are there in all their completeness. … No account of the universe in its totality can be final which leaves these other forms of consciousness quite disregarded.” —

Alzheimer’s blood tests may be misleading for people with kidney problems
“Alzheimer’s blood tests may be misleading for people with kidney problems.” Summary: “A large study found that people with impaired kidneys tend to have higher Alzheimer’s biomarkers, yet they don’t face a higher overall risk of dementia. For those who already have elevated biomarkers, kidney problems may speed up when symptoms appear. The findings show that kidney health can change how Alzheimer’s blood tests are read. Doctors may need to consider both organs to get a clearer picture.” Pair this article with my brand-new conversation with Dr. Tommy Wood on preventing dementia.— Tim Ferriss

My appearance on The Shawn Ryan Show. Shawn is a former U.S. Navy SEAL and CIA contractor who served for 14 years across multiple combat missions.

How I Beat Lyme Disease with The Ketogenic Diet
“How I Beat Lyme Disease with The Ketogenic Diet.” I started writing this as a reply on X to Greg Yang, co-founder of xAI, who recently stepped down from xAI to address his debilitating case of Lyme disease.

But eventually, these products turn into something else: tiny synthetic particles that spread quite literally everywhere—into our air, our food, our water, even inside of us. We are only beginning to tease out what the presence of these microplastics means for our health—and what we can do about it.” I hope to have more thoughts later this year about how to deal with PFAS “forever— Tim Ferriss

Burden of Dreams
Burden of Dreams (Amazon, Apple TV). This documentary was recommended to me by one of the most phenomenal artists I know, Dustin Yellin. Burden of Dreams is a strange and captivating film. It’s a showcase of tackling the impossible, being unrealistic, and failing above others’ successes. On so many levels, the compulsion, single-mindedness, and all-or-nothing drive of legendary filmmaker Werner Herzog makes no sense. And yet… to me, parts of his journey, and parts of his worldview, make all the sense in the world. This is a bizarre one that will only appeal to a small fraction of you, but here— Tim Ferriss
