Radioactive isotopes are used to measure fossils and other artifacts. While an organism is alive, it takes in isotopes. Once the organism dies, the isotopes do not enter the body anymore. Scientists can estimate how much of the radioactive isotopes were present in the body to begin with and then determine how much is currently left.

Get the radiochemical datingmug. Fictional rules invented by girls to confused guys, during a relationship. Generally, these rules contradict eachother, and it is impossible to follow them correctly.
There is the common "statement" form, encountered when an action is illegal:
"John! You moved my lettuce to shelf four of the refridgerator! that is so against the rules!"
Also common is the "impossible question" form, where no correct answer is possible:
"Tim. Does this dress make me look fatter than normal?"
"Do you know what day it is today?"
Rare, but still worth mentioning, is the "invented" form:
"This form was invented to fill up some space on the page"
"John! You moved my lettuce to shelf four of the refridgerator! that is so against the rules!"

Get the dating rulesmug. A politically correct and evasive term for racist dating
Many people come up with this as an excuse to only date particular races because they "cannot help being attracted to a specific group of people"
The UN defines racial discrimination as "any distinction, exclusion, restriction or PREFERENCE based on race, colour, descent, or national or ethnic origin ..."
Believe it or not, many people also refuse to date their own race/ethnicity - that is also racist, no matter how you look at it

Get the Dating Preferencemug. A date for prom/other social gathering that asks you to go with them and then disappears into obscurity and avoids contact with the person they asked until said event.

Dude 2: "Ummm, I have no idea Dude 1, I think its Chad"
Dude 1: "Oh yeahh, Chad asked her like two weeks ago but they haven't seemed to talk since..."
Dude 2: "That's mad awk man, hes such a Deadbeat date to her."
