If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.

NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

Everyone, red state, blue state, everyone supports space exploration.

I guess I can be surprised I'm alive. I'm taking a little better care of myself than when I was a young person. My father died when he was 63. My mother made it to 74. My grandparents, God, they were dropping like flies.

Science is, rightly, searching for drugs to arrest ageing or to slow the advance of dementia. But the evidence suggests that many of the most powerful factors determining how you age come from what you do, and what you do with others: whether you work, whether you play music, whether you have regular visitors.

I like to branch across a lot of different styles and brands in the way I dress; it's just the way my style works. So I love that I can walk into a Target store and think, 'Oh my God, I love these jeans,' and then I'll pair them with something designer.

I do believe there's a heaven. I do believe that God has given me the resilience and the survival skills to withstand the chiffon trenches.
