omg this guy Chris Williams is like a superhero in space 
! i mean, he's got a PhD in astrophysics and experience as a firefighter... talk about a diverse skillset 
! plus, he gets to spend 8 months on the ISS conducting science experiments and pushing the boundaries of human knowledge... that sounds like an amazing adventure to me 
! i hope they get some awesome space selfies with the cosmonauts too

I mean, sure Chris Williams is a medical physicist and all that jazz, but have we seen his research papers or credentials? 
Also, why do we need to replace 3 Russian cosmonauts every year? Sounds like a pretty hefty price tag for taxpayers... 
what's really going on behind those Soyuz doors?!
