The title comes from the Tempest by Shakespeare. From the words of Prospero, in the famous passage: “we are such stuff as dreams are made on”
“Our revels now are ended. These our actors, As I foretold you, were all spirits and Are melted into air, into thin air: And, like the baseless fabric of this vision, The cloud-capp’d towers, the gorgeous palaces, The solemn temples, the great globe itself, Ye all which it inherit, shall dissolve And, like this insubstantial pageant faded, Leave not a rack behind. We are such stuff As dreams are made on, and our little life Is rounded with a sleep. Sir, I am vex’d; Bear with my weakness; my, brain is troubled: Be not disturb’d with my infirmity: If you be pleased, retire into my cell And there repose: a turn or two I’ll walk, To still my beating mind. (4.1.146-163)”
Here is one example:
Seventeen weak subgroup discrepancies were found in 86,687 donors units tested, making an overall incidence of 1:5,100 donors or 0.02%. Correct blood typing and labeling of an individual as donor and as a recipient is essential to prevent ABO incompatibility in case of weaker subgroups of A and B.
