Former astronaut works the other side of the game.
[QUOTE]This has long been the promise of Chang-Díaz’s plasma-based VASIMR rocket engine.[/QUOTE][/QUOTE]I actually had a chance to speak with him about this in the early 1990's (if memory serves). He was at an event that I attended. I stayed after and spoke with him. He is was the second astronaut that I have seen in person (not counting 2 ant like creatures seen across a dry lake bed.) I have added a few more since and talked to Apollo era ones.

I think a lot of biases come into play as well as the fact that one set of symptoms could be 20 different things ( all a syndrome is classed as is a set of symptoms, I know the one I grew up with can have a good 5+ causes at the very least for example).

Since the International Space Station was completed well before it's deadline and costs only a fraction of the the budget, lets build a lunar space station....

That is some really interesting research. I have observed that pants which are long enough to pile up a bit, especially on shoes or boots with higher tops, are very good at untying laces. I have often resorted to double knotting in this situation.

My most recent pair of boot/shoes has a clever dodge which seems to fight untying. The laces have some quite shiny fibers braided into them. These fibers are a bit harder than the rest of the lace, causing them to stick up more. They tend to catch on each other, effectively increasing slip resistance. This particular pair has to be laced quite loosely to avoid pressure that hurts my ankle bones. I would not be able to keep them tied with common round laces.
