Did Scott and Mark Kelly eat the same foods during this experiment? Did NASA track the food input for both of the brothers so that there would be less variations between their environmental conditions, so that the experiment could be more concentrated on the aspect of gravity or the lack thereof?

Just a person wanting to help ... Balance is important in all of our lives, if you are passionate about something go for it, though don't let your self be torn down by your goals, instead breath, smile, and think... I am already so far beyond what so many other people are in some of this knowledge. You are going to do great I just know it 😊

Can there be an environment adjustment to have a higher oxygen concentration on the ISS? Thank you for responding to my question :)

On the issue of microgravity, extra blood flow and blood volume in the head can cause headaches, correct? What are the headaches caused by, is it just the increased intracranial pressure or is there a heat factor causing pain? Also what kind of headaches do the astronauts have? Migraine? Tension? Is their head hurting all of the time, or does the pain go away? Does NASA currently allow headache /migraine headache sufferers to become astronauts? And have they done any studies on the effects of microgravity on people who already have headaches?
