Back in 1990 I attended a conference where Neil Armstrong spoke, it was and ok speech. Even he admitted it wasn't his favorite thing to do. He got very serious about halfway through and talked about the depression he suffered once back and how it was very tough to embrace reality and little things. It took him a while to feel whole again and that there was much more to life, he said. he commented that he felt empty for some time. Then he shifted gears and talked about the space program i general and why its important to explore not only in space but here on mother earth.
