Things do not happen. Things are made to happen.
The most effective way to do it, is to do it.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
Only the educated are free.
If you think you can do it, you can.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
If you've got a talent, protect it.
Know or listen to those who know.
There's a lot of interest from the medical community on how things develop in microgravity, and the hope, later, that is expected to apply to what the changes are in humans as well.
