# half life

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.

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.
