1. Trip way too long/cramped/complicated.
2. Biologically way more suited to Earth.
3. Robots doing good job as it is.
4. Don’t want to repeat same mistake I made when I led 4-man mission to Vegas.
5. Unwillingness to follow dreams, let alone pipedreams.
6. Tendency to panic, crawl up in corner, and hyperventilate when things go wrong.
7. Like my mother says, "Mars Schmars".
8. Face on Mars proven to be just an optical illusion, not entrance to alien space station.
9. Would preferably not want to run the risk of enduring a slow, painful, suffocating death while trapped in a metal can thousands of miles from earth.
10. Not an astronaut.
