And second, medical space research may revolutionize the technology and the techniques of modern medicine. Whatever new devices are created, for example, to monitor our astronauts, to measure their heart activity, their breathing, their brain waves, their eye motion, at great distances and under difficult conditions, will also represent a major advance in general medical instrumentation. Heart patients may even be able to wear a light monitor which will sound a warning if their activity exceeds certain limits. An instrument recently developed to record automatically the impact of acceleration upon an astronaut's eyes will also be of help to small children who are suffering miserably from eye defects, but are unable to describe their impairment. And also by the use of instruments similar to those used in Project Mercury, this Nation's private as well as public nursing services are being improved, enabling one nurse now to give more critically ill patients greater attention than they ever could in the past.

But let me say, with respect to other countries, that I am wholly opposed to the state being used by any religious group, Catholic or Protestant, to compel, prohibit, or persecute the free exercise of any other religion.
