Some questions I don't know the answers to.
Would appreciate pointers to references which can help answer or some philosophizing on the right answer.
- Has economic mobility significantly changed over time?
- What is the expected lifespan of human organs? I read somewhere on the Internet that lungs are expected to last 60 - 70 years but our brains could go to 120 years?
- What is the embodied energy cost of popular motorized vehicle transport mechanisms?
Since my questions page is not very intersting (yet), here are some other people's questions pages.
- Patrick Collison, co-founder of Stripe. I really like his first question.
