Strangers sat next to each other, separated by a thin wall, and were asked to answer the question - 'if you could make one wish come true, what would it be?'
What most of them did not know was that the person on the other side of the wall was either someone who had some form of leukemia or had a family member who had it.
And this reflected in the answers they had for the same question. Have a look.
