Low-dose tadalafil (2.5–5 mg/day) supports prostate health, boosts blood flow, increases androgen receptor density (like L-carnitine does), and cuts nighttime urination episodes in half — improving sleep, which in turn raises growth hormone and testosterone.

A tightly packed segment on alcohol unpacks its triple threat to testosterone. First, the aromatase connection: alcohol significantly and dose-dependently up-regulates aromatase, the enzyme that converts testosterone into estrogen. Second, the neurological angle: alcohol is highly GABAergic, activating inhibitory neurotransmission in a way that suppresses LH and FSH release from the pituitary — a mechanism Gillett explicitly compares to opiates. Third, the metabolic hit: at 7 kilocalories per gram, alcohol carries nearly the caloric load of fat (9 kcal/g), adding to body fat accumulation that further amplifies aromatase. Gillett's practical recommendation is no more than 3–4 standard drinks per two weeks — and notes that one large glass of wine likely counts as about 5 standard drinks.
Alcohol significantly increases aromatase activity, converting testosterone to estrogen. It's also highly GABAergic, suppressing LH and FSH release much like opiates do. And at 7 kcal/gram, it's nearly as calorie-dense as fat. Dr. Gillett recommends no more than 3–4 standard drinks per two weeks.

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.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
