The plastic lining inside paper cups starts leaching BPAs, BPS, and microplastics as soon as hot liquid is added. The simple fix is to pour hot drinks into a ceramic or stainless steel mug as soon as possible — or better yet, bring your own travel mug.

'Microwave safe' only means plastic won't melt — it still leaches BPAs. Paper cup linings leach BPAs and microplastics into hot beverages [1] — Andrew Huberman "The plastic lining inside paper cups starts leaching BPAs, BPS, and microplastics as soon as hot liquid is added.

A 2024 PNAS study using improved microscopy found bottled water contains an average of 240,000 microplastic and nanoplastic particles per liter — up from a prior estimate of 30,000. The jump wasn't because water got dirtier; better tools revealed particles that were always there but invisible to older methods.
A 2024 PNAS study using improved imaging found bottled water contains on average 240,000 microplastic and nanoplastic particles per liter, far exceeding the prior estimate of 30,000.
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.
