Idle

Idling is the root to all depressions.

When an old person becomes idle, they have nothing do do, no where exercise their brain power, they'll suffer from amnesia?

When a person suffering from relationship or work problems starts to get idle, they dwell upon it, and possibly get tangled in the down-leading spiral.

Pretty much like a car huh? Idling for excessive period of time will cause them to require more frequent maintenance.. lol...

So, what are you waiting for? Get yourself occupied!! :D
