— What do you think, how heavy is this glass? ...
Approximately 200 grams! No, 300 grams, perhaps!
— I do not know for sure until it weight. My question is: what will happen if I will keep the glass for a few minutes?
— Nothing!
— Really, nothing terrible will happen, "said the professor. – What will happen if I get to keep the glass of the outstretched arm, for example, two hours?
Is your hand will ache.
— And if all day?
Is your hand is numb, "said one of the students.
— In your opinion, the weight of the glass changes from what I will keep all day?
— No! -bewildered students responded.
— And what to do to fix it?
-Just put the glass on the table! -fun told one student.
— Sure! – happily answered the professor.
And what is with all of life's difficulties. Think of any problem a few minutes and it will be next to you. Think about it a few hours and it will start you suck. If you are going to think the whole day, it paralyzes you.
