Hi Annie,
Thanks fot the FDK!
I liked the scientific stuff on both hitting the asteroid and running out of air. You obviously did a lot of research.
Actually, I didn't need to research this. I have been a scientist, virtually all of my life so it comes naturally, thanks to all of the study I have done over the years. As far as the oxygen deficit, that is basic anatomy and physiology. I have been involved in emergency medicine for more than 30 years and am a paramedic trained EMT.
