Is Polar Bear Evolution the KEY to Unlocking a Longer Human Lifespan?

I took the Amtrak train (the California Zephyr) from Chicago to Iowa for the first time and this was my experience! I’d recommend it if you’re looking for public transportation options in the US since the seats were really comfortable, the observation deck was really cool, and there’s a cafe & bar. There’s also VIP rooms and beds if you’re willing to spend more. #amtrak #californiazephyr #chicago #iowa #travelusa
