The students’ answers 23 from 20g to 500g.
“It does not matter on the absolute 24 . It depends on how 25 you hold it. If I hold it for a minute, it is OK. If I hold it for a(n) 26 , I will have an ache in my right arm. If I hold it for a day, you will have to 27 an ambulance. It is exactly the 28 weight, but the longer I hold it, the 29 it becomes.” The whole audience became silent, lost in thought.
After a moment, the lecturer continued, “ 30 we carry our burden all the time, 31 , we will not be able to carry on with the burden becoming increasingly heavier, 32 heavy for us to bear.
“What you have to do is to 33 the glass, rest for a while 34 holding it up again.”

So before you 36 home from work tonight, put the burden of 37 down. Don’t carry it back 38 . You can pick it up tomorrow.
Whatever burden you are having now on your 39 , let it down for a moment if you can.
