great conversation. I would really like that during my life, scientists would find evidence of life outside our planet, that's one of my dreams. Regarding the life an death conversation, I was surprised that having children ( as it's the case with Sarah) wasn't mentioned. If you have 1 year to live and you have small children , I think the question is quite simple to answer. Children should be our priority, in my case, I would quit my job ( I can do it).
