天生犯罪人是其有机命运的奴隶。
Uncertainty is not an excuse for inaction.
I would like to fly in space.Absolutely.That would be cool.I used to just do personally risky things, but now I’ve got kids and responsibilities, so I can’t be my own test pilot.That wouldn’t be a good idea.But I definitely want to fly as soon as it’s a sensible thing to do.
