Body

The body is the first instrument and the last. Every claim in the longevity literature has to survive contact with what one does with one's own carcass on a given Wednesday. Most claims do not.

Writing under Body asks a narrow question: what practices, when run over years, produce a body capable of long, attentive work and recovers well between bouts? The answer is less than the supplement industry believes and more than the productivity-via-coffee crowd allow. It is closer to what the old physicians and the contemplative traditions converged on, which is to say: sleep, walk, lift, breathe, eat plants, and treat sun and cold as nutrients rather than as enemies.

The stream takes seriously the somatic substrate of cognition. A nervous system parked too long in sympathetic dominance will not produce good sentences, regardless of how good the writer thinks she is. The exercises that calm it down — breath work, slow strength, long walks — are not adjacent to the work of the mind. They are part of it.

What Body refuses: protocol culture; the conflation of self-tracking with self-knowledge; any sentence that begins "biohack." Self-experimentation is a discipline with three hundred years of practice behind it. It deserves to be done in that lineage and at that level of seriousness.

The thread between Body and the other streams is that all four are investigations of the same substrate, approached from different sides.
