One day, two students were in a room.
One was studying medicine & the other was studying accounting.
The one doing accounting, was cleaning his wardrobe and suddenly,
he saw ants coming out and going into his wardrobe.
As he was checking for the cause of the invasion, he saw that there was a packet of sugar in his ward.
He opened it, and saw that some were dead.
He asked the medical student for the reason the ants are dying,
the medical student replied "May be they died of diabetes." :D
