.A professor began his class by holding up a glass with some water in it. He held it up for all to see and asked the students,:
-'How much do you think this glass weighs?'
-'50 gms!'.... '100 gms!'...... '125 gms' ...... the students answered.
-'I really don't know unless I weigh it,' said the professor, 'but, my question is: What would happen if I held it up like this for a few minutes?'
-'Nothing' the students said.
-'Ok! What would happen if I held it up like this for an hour?' the professor asked.
-'Your arm would begin to ache', said one of the students.
-'You're right, now what would happen if I held it for a day?'
-'Your arm could go numb, you might have severe muscle stress and paralysis and have to go to hospital for sure!' ventured another student; and all the students laughed.
-'Very good. But during all this, did the weight of the glass change?' asked the professor.
-'No'
-'Then what caused the arm ache and the muscle stress?' The students were puzzled.
-'Put the glass down!' said one of the students.
-'Exactly!' said the professor. 'Life's problems are something like this. Hold it for a few minutes in your head and they seem okay. Think of them for a long time and they begin to ache. Hold it even longer and they begin to paralyze you. You will not be able to do anything'.
