Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
Never complain and never explain.
You never know what motivates you.
What you do today can improve all your tomorrows.
Who seeks shall find.
The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
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.
