Half-Life is a revolutionary game for computer; more need not be said.
An element's half life is the period of time it takes for half of the radioactive isotopes to decay. It is ibnot/b/i used to describe the dissapation of something not radioactive(subliminal hintcaffeine for instance /subliminal hint)

The half life of a radioisotope is the time taken for the current level of radioactivity to drop to half that amount. Note that this means radioactive decay follows the curve of a decaying exponential. Oh, as mentioned, it is also somewhat of a revolutionary computer game. "As for the suit, I think you've earned it"
Carbon-14 has a half-life of 5,730 years. Let's say its radioactivity 'level' at time = 0 is 2. After around 5,730, its radioactivity will be 1, After a further 5,370 years its radioactivity will be 0.5, and after yet another half life, the radioactivty would be 0.25, and so on.

1. The length of time needed for half the atoms of a radioactive isotope sample to decay
2. A sweet game

A very good computer game that gets abused by HALO zombies. Basic single player owns. Got lots of addictive mods.

One of the most addictive games after Counter-strike and World of warcraft.most of the players are individuals from 5 years to 25 years old and are those who play up to 8 hours a day are called ironiclly "half-lifers" because they have a"half-life" by playing that long.
Dude 1: hey what are you doing?
Dude2:nothing, playing half-life
Dude 1: how long?
Dude 2: 9 HOURS STRAIGHT
Dude 1: you such a half-lifer
