1. In case of Multiple Personality Disorder, the transformation from one personality to another is characterized by facial acrobatics that can give Cartoon Network and Jim Carrey [or Animorphs] a run for their money, and special effects that wouldn’t seem out of place in Star Wars.
2. The aforementioned patients speak in tongues and accents hitherto unknown to them.
3. Psychological ailments are always diagnosed in less than a session. If it is spread over many sessions, it always leads to a doctor-patient relationship.
4. Bullet-wounds lead to instantaneous death for the villain [but not before he repeats his catchphrase atleast once, or has conceded defeat]. If much work needs to be done by the hero, no amount of ammunition is enough to stop him from keeping that promise to his bestfriend/fatherinlaw/maa.
5. No loss of blood is too much for the hero who can lose as much blood as a vampire’s 10-course dinner and still manage to dishum-dishum the villain’s cronies [one of whom will be big-bodied and bird-brained], rescue the heroine from the jaws of death [or villain] and kill the villain/hand him over to the authorities.
6. Heart patients can run for miles on end without rest and end up with only a cough or wheeze. Death is never a side-effect.
7. Victims of Cancer always cough out blood, irrespective of the type of cancer or stage at which the disease is.
8. When equipment is unavailable, the hero performs mouth-to-mouth resuscitation on the heroine which happens to be a case of Kiss mein kitna hai dum.
9. And this is mostly required in cases of drowning, usually preceded by another exercise to pump out water swallowed in the course of the swim.
10. A knock on the head results in memory loss, loss of mental balance and in extreme cases, amnesia.
11. Other known causes of amnesia and loss of mental balance are near-fatal accidents, near-fatal brushes with the villain, electric shocks, shocking news.
12. The cure is normally a second knock on the head or any of the aforementioned causes. It can also be the sight of an ex-lover, sibling/other family members or the rendition of the family/love song.
13. Hospital stays are never completed for there is always Work [read dishum-dishum] To Be Done outside. And the bandages around the head [with a spot of blood on] or around the wrist pose no problems ever.
Just a general observation: beds have unique L-shaped blankets that cover the woman upto her underarms, but the man next to her only till his waist.
Well, I guess bending medical science to suit the plot only goes on to show that story and script rule in tinseldom after all.
