Genetic Inheritance

  1. FADE IN.


  2. Act 1


  3. INT. STUDY - DAY


  4. Checking his phone notifications, PETER pauses.


  5. PETER (V.O.): Here's an interesting question from a Quoran: Which of your relative's lifespan is most likely to predict how long you'll live?


  6. Pausing.


  7. PETER (V.O.) (Cont'd): I've read something about the X-chromosomes and the Y-chromosomes...I believe I look and smile like my Mom.


  8. Pausing.


  9. PETER (V.O.) (Cont'd): It's a scientific question after all.


  10. Peter surfs the web.


  11. PETER (V.O.) (Cont'd): My DNAs have 50% of my Dad's genes and 50% of my Mom's genes.


  12. Thinking.


  13. PETER (V.O.) (Cont'd): Nature's design is really amazing. So fair.


  14. Act 2


  15. INT. STUDY - CONTINUOUS


  16. Reading.


  17. PETER (V.O.) (Cont'd): But male genes are more aggressive, and therefore they're more prominent.


  18. Reading.


  19. PETER (V.O.) (Cont'd): And the sex of a future baby depends on the father as he has both the X-chromosomes and the Y-chromosomes, while the mother only X-chromosomes.


  20. Reading.


  21. PETER (V.O.) (Cont'd): I'm male, as I got both the X-chromosomes and the Y-chromosomes.


  22. Reading.


  23. PETER (V.O.) (Cont'd): If a father has more brothers, he's likely to have more sons and vice versa...Interesting.


  24. Thinking.


  25. PETER (V.O.): My Dad had two brothers and one sister. He had four sons and one daughter.


  26. Pausing.


  27. PETER (V.O.) (Cont'd): Quite right. I should have more sons than daughters then.


  28. Pausing.


  29. PETER (V.O.) (Cont'd): I stopped at half-and-half. That' s fair, consistent with nature's design.


  30. Reading.


  31. PETER (V.O.) (Cont'd): The genes responsible for intelligence are contained in the X-chromosomes...and therefore I've inherited my intelligence from my Mom?


  32. Pausing.


  33. PETER (V.O.) (Cont'd): My Mom had only primary school education. My Dad too. They're classmates and married before the age of 20.


  34. Thinking.


  35. PETER (V.O.) (Cont'd): I think I behave more like my Dad, disciplined and creative.


  36. Reading.


  37. PETER (V.O.) (Cont'd): Scientifically, it's my Dad's genes that impact on my health.


  38. Recalling.


  39. PETER (V.O.) (Cont'd): My grandpa lived to the age of 62 with unhealthy habits. My Dad didn't have any unhealthy habits and lived to the age of 80.

  40. Reading.


  41. PETER (V.O.) (Cont'd): Scientists speculate that in the first 70-80 years of age, lifestyle is the strong determinant of health and lifespan. It's only after the age of 80 and beyond would genetics play a progressively important role.


  42. Pausing.


  43. PETER (V.O.) (Cont'd): Hong Kong has the highest life expectancy in the world.


  44. Peter surfs the web with his mobile.


  45. PETER (V.O.) (Cont'd): In Hong Kong, the average life expectancy for men is 81.3 years of age and women at 87.3.


  46. Recalling.


  47. PETER (V.O.) (Cont'd): My Dad died at the age of 80 and my Mom is still alive, living beyond 87.3.


  48. Recalling.


  49. PETER (V.O.) (Cont'd): Today is October 5. I first got married on this date in 1979. I didn't intend to have any children, as life was hard.


  50. Sighing.


  51. PETER (V.O.) (Cont'd): But my first wife died untimely, at the age of 36.


  52. Sighing again.


  53. Act 3


  54. INT. STUDY - CONTINUOUS


  55. PETER (V.O.) (Cont'd): I've internalized my late wife in me; and I think nature should be fair to us.


  56. Pausing.


  57. PETER (V.O.) (Cont'd): But that's only wishful, unscientific thinking.


  58. Thinking.


  59. PETER (V.O.) (Cont'd): To predict how long will I live, I've to follow science.


  60. Reflecting.


  61. PETER (V.O.) (Cont'd): All factors considered, I predict that I can live to the Hong Kong average ie 81.3 years of age.


  62. Counting fingers.


  63. PETER (V.O.) (Cont'd): So, that's about 15 years from now. I thank my late Dad and my Mom for giving me life.


  64. Peter types his answers on his phone.


  65. FADE OUT.


  66. THE END
