After his first successful TMS treatment, Tim Ferriss couldn't ejaculate for two weeks. His doctor had never seen it before and attributed it to over-suppressing the sympathetic nervous system. The good news: anxiety gone. The bad news: something else gone too. Eventually it resolved — and now he knows to expect it as confirmation that the treatment worked.

Tim Ferriss used accelerated TMS combined with the neuroplasticity agent D-cycloserine to drop his generalised anxiety and OCD rumination from an 8-9 out of 10 to near zero — in a single day. The effects lasted three to four months. It changed how fast he fell asleep, how easily he meditated, and how he processed the friction of daily life.
The UK had 12,183 arrests for posting on social media in 2023 — nearly double second-place Belarus — according to Freedom House statistics cited in The Times.
A stellate ganglion block involves an ultrasound-guided anaesthetic injection into a nerve bundle in the neck, essentially shaking the etch-a-sketch of your sympathetic nervous system. Chris Williamson tracked a 30% overnight increase in HRV that held for months. It's primarily used for PTSD in soldiers. You do one side, wait, then do the other — because both at once would shut down half your face and throat.
Chris Williamson tracked a 30% overnight increase in HRV after a bilateral stellate ganglion block, which held for several months before gradually declining.
After his first effective TMS treatment, Tim Ferriss was unable to ejaculate for two weeks — a side effect attributed to over-suppressing the sympathetic nervous system.
Most non-invasive vagus nerve stimulators don't hit the nerve correctly. The nerve fibres barely reach the ear, and most ear-based devices aren't positioned in the right spot — the cymba concha. The neck-based devices are more promising and are FDA-cleared for migraines. But Setpoint Medical's implant — the size of an omega-3 capsule, inserted as an outpatient procedure — is the real frontier.
Anxiety is not fear. Fear has an object — a wolf, a threat. Anxiety is the vertigo of standing at the edge of infinite possibility and knowing that choosing any one thing closes off all the others. Kierkegaard argued that the depth of your anxiety is proportional to the depth of your potential.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
