Monetization
Estimated X creator earnings
$24–$58 in the last 30 days
From 4.9M views on @davidasinclair's original posts in the last 30 days.
Rewards eligibility: likely
Rough estimate. X publishes no payout rate, so this assumes about $5–12 per 1M original-post impressions from reported creator payouts. Only Premium viewers’ impressions count, so real payouts can be much lower.

It’s confusing. Some studies examine sildenafil (Viagra), others tadalafil (Cialis). So many new studies are indicating surprisingly positive effects on various organs & even immune cells fighting cancer. How about a new Lifespan episode called “What’s not to love?”

Could gut bacteria from long-lived people be used to treat Alzheimer's (AD) & aging? NMN-producing bacteria from healthy older adults were tested in a worm model of AD. Lifespan was extended & behavioral deficits were less 🪱💪😋 What if we ate them? https://t.co/okg2MXF6IW

Scientists can't simply remove enemies from their lives. The "peer review" system allows competitors & colleagues for decades to anonymously decide if a scientist's work should get published and their grants funded. Without papers and grants, a research career is toast 🔥
