Baa #1

One night when we were chillin at Uncle Bob's place, when his attempts to turn on the air-conditioner fails. When further persuasion fails, it drew out this gem of advice:

Bald Monk:
Bob, how long have you you had this air conditioner?

Bob:
Probably 10 or so odd years, why?

Bald Monk:
Ah. And there lies your problem!
When was the last time you blew air into the air conditioner?

Bob:
Wait.. what?

Bald Monk:

Bob.
For the past 10 years, the air cond has been diligently spewing cold air.
And yet, for the 10 years, you have not see to it that the air cond gets air blown into it.
The air cond is now not working simply because it ran out of the supply of air it initially came with due to your negligence.
To fix it, all you have to do is stick a tube/pipe into the air cond and blow air into it.
If you want to use the device for another 2 years, blow another 2 years worth of air into it!
It's really that simple!
