Winning is everything in the red traffic light game. Win a simple game of 'paper scissors rock' (just one game - best of one) and your loins will be titillated with a dash of frothiness thrown in too if you're lucky. At every red light you stop at whilst driving, the loser must'
fondle/stroke/touch/use their hands/finger-bang/fist?/ the winner for as long as the traffic light is red. (no fist please). Once the traffic light turns green, all action must stop. Repeat at next red light.

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.
