No Gain Syndrome or NGS, is a term used to describe people who start going to the gym for the first time on a regular basis who truly believe they are experience no gains in muscle mass.

Of course it is all in their heads, and NGS usually subsides after 6-8 months of solid lifting.

This syndrome can sometimes be followed by the 'I need to start using gear because, that guy is bigger than me complex'.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
