"People who have metal implants should be familiar with the symptoms of radio wave sickness and should keep their environment free of wireless radiation producing products."

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."
