It's been nothing short of comical to see those who hate Trump making the claim the astronauts were not stranded but that another spacecraft was available to bring them back to Earth. That equates to saying a ship has a single lifeboat and there's a good chance it will take on water. These are people who would claim they're not stranded on the crapper because they believe eventually someone will bring them another roll.
I was impressed by the positive attitude they had… at least in from of the camera. Would have been easy to freak out a bit. Those that space travel are a special breed.
I was surprised by the amounts of muscle mass and bone density loss percentages. It takes a different mindset knowing that you're not going to be able to walk when returning to Earth. Something else that was mentioned was about the difficulty the body has in processing liquids.
