Your "speed work" is too slow. Unless you're listening to these ridiculous influencers telling you that all you need to do is "sprint"... In that case, your speed work is too fast.

This is biblical. A woman in her eighties. Ten years into Alzheimer's. Hadn't spoken a full sentence in five years. Takes one, 5 gram dose of psilocybin. She slept 19 hours and woke up and spoke for hours about her life, recognized family and held real conversations. She regained bladder control after five years, walked on her own. and dressed herself. Gains held for weeks.

... 🤔 The medical literature contains another highly specific, documented case report regarding transient neurological restoration in advanced dementia using a psychedelic protocol. The Beckley Foundation recorded the clinical response of a 97-year-old female patient diagnosed with concurrent Alzheimer's disease and vascular dementia eleven years prior to the intervention. The patient presented with severe neurodegeneration, existing in an established apathetic and near-vegetative baseline state. The clinical team initiated a sustained microdosing protocol utilizing lysergic acid diethylamide (LSD). According to the Beckley Foundation's case documentation, caregivers and attending medical personnel recorded the immediate restoration of spontaneous conversational speech, active reading comprehension, and reciprocal social engagement following the initial administration. The patient maintained these restored cognitive functions throughout the final four months of her life via the continuous LSD microdosing protocol. 🤔

Just for those who might not know, I'm not a weight-loss coach. I train high-level endurance athletes with competitive goals. Come to think of it, none of them are fat. Maybe I need a side hustle... How's this for a pitch? "Come train 20-30 hours a week with me & you won't be fat."
Scared you entire identity is being challenged?

...🤔 I wonder if triggering muscle protein synthesis has any differential effect on satiety?

“Perfectly combining” plant proteins is still inferior to animal proteins when it comes to muscle protein synthesis: ajcn.nutrition.org/article/S… (and let’s face it, it’s just EASIER to eat a steak than it is to wander around the kitchen mixing up the right ratios of beans, nuts, seeds, rice, grains, etc.).

💪😎☕️ so a strong coffee before your #workout can blunt the effects of creatine

Is it ok to combine creatine with caffeine? They are generally not a problem together unless your caffeine dose is very high. The interference seems to show up around ~350 mg of caffeine pre-workout (about 3.5 cups of coffee), where caffeine may blunt some of creatine’s performance benefit because they have opposite effects on muscle relaxation. So yes, you can put creatine in your coffee (I do). Just don’t mega-dose caffeine before training if you want the full ergogenic effect. Even then, the effect is probably minor enough to not stress about.

In the short-term, we're more fragile than we want to admit. In the long-term, we're more adaptable than we think.

Chewing gum can shed microplastics into saliva: acs.org/pressroom/presspacs/…  (an average of 100 microplastics released per 4 min chewing a gram of gum, and some gum pieces released as many as 600 microplastics per gram)
