Employee Half-Life

The Employee Half-Life of a workplace is the amount of time it takes for half of a new batch of employees to quit.

An EHL of less than three months is generally regarded as a bad sign in business.
When I first joined Acme Industries, there were five other new employees with me. After about six weeks, only three of us remained, including myself. So Acme Industries has an Employee Half-Life of about six weeks.

half life 2

is overrated game that tried to be hollywood blockbuster but turned out mediocre and boring FPS with barely any reedemable features. The only person who likes this game is Gabe Newell and Nobody.

Half Life is only remembered due to Half Life 3 meme since the game has never reached an actual ending and ended on half Life 2 episode 2 dlc.
However, Half Life itself is a boring name for the title because it is some Physics terminology that will make you go to sleep. Thankfully, Lives only have two halves.
Person 1: Hey I hope they will make a sequel to half life 2.
Person 2: But it already exists, it's called garry's mod and its better anyways.
Person 1: oh right

The Half-Life of Singapore Math

The time it takes for the bar model method, the heart and soul of Singapore math, to become a common feature in most math curriculums around the world, which implicitly means that it no longer holds the competitive edge over other developed nations in math education.
With pirates from both developing and developed countries leveraging on AI, the half-life of Singapore math is getting exponentially shorter, and the “fine” city of Singapore risks being innovated away if local math educators don’t act now.
