Luckily, my caffeine-deprivation headaches are just a standard tension headache/possible lead-in to mild migraine for me. But then I have ADD and caffeine has nearly zero effect on my energy levels, etc. It helps me focus my attention a bit better I think.
Shakespeare's most striking departure from Cinthio is the manner of his heroine's death. In Shakespeare, Othello suffocates Desdemona, but in Cinthio, the Moor commissions the Ensign to bludgeon his wife to death with a sand-filled stocking.
Othello is the most famous literary work that focuses on the dangers of jealousy. The play is a study of how jealousy can be fueled by mere circumstantial evidence and can destroy lives. (In Othello, the hero succumbs to jealousy when Iago convinces him that Desdemona has been an unfaithful wife â in the end, Othello murders his wife and then kills himself.) It is interesting that Iago uses jealousy against Othello, yet jealousy is likely the source of Iago's hatred in the first place. In Othello, jealousy takes many forms, from sexual suspicion to professional competition, but it is, in all cases, destructive.
