  3. 6308 0:06 - 0:08
    Death sucks.
  4. 7756 0:08 - 0:10
    [Bus honking]
  5. 10004 0:10 - 0:12
    But what happens to your body after you die
  6. 12263 0:12 - 0:14
    is fascinating.
  7. 13575 0:14 - 0:15
    So we're going to show you.
  8. 15070 0:15 - 0:16
    Don't worry. It won't be gross.
  9. 16564 0:17 - 0:18
    Much.
  10. 17711 0:18 - 0:20
    Once a person's breathing stops,
  11. 19737 0:20 - 0:22
    the cells in their body stop receiving oxygen.
  12. 22365 0:22 - 0:24
    But the cells continue to live
  13. 23957 0:24 - 0:25
    for several minutes,
  14. 25139 0:25 - 0:27
    generating carbon dioxide.
  15. 26969 0:27 - 0:29
    Carbon dioxide is acidic
  16. 28784 0:29 - 0:30
    and it builds up,
  17. 29867 0:30 - 0:32
    rupturing sacs inside the cells.
  18. 32002 0:32 - 0:34
    These sacs contain enzymes
  19. 33973 0:34 - 0:36
    that begin to digest the cells
  20. 36145 0:36 - 0:38
    from the inside out.
  21. 37829 0:38 - 0:40
    This creates a blister-like fluid
  22. 39736 0:40 - 0:41
    rich in nutrients.
  23. 41196 0:41 - 0:43
    After about a week, those nutrients
  24. 43353 0:43 - 0:45
    fuel an army of bacteria
  25. 44990 0:45 - 0:46
    and fungi that further
  26. 46336 0:46 - 0:48
    liquefy organs and muscles.
  27. 48256 0:48 - 0:50
    The microbes that attack the tissue
  28. 50270 0:50 - 0:52
    produce a bewildering array
  29. 51841 0:52 - 0:54
    of more than 400 chemicals and gasses.
  30. 54111 0:54 - 0:55
    They include:
  31. 54790 0:55 - 0:58
    Freon: that's right, the coolant found in refrigerators.
  32. 57770 0:58 - 1:00
    Benzene: a powerful component in gasoline.
  33. 60410 1:00 - 1:03
    Sulfur: which smells of swamps
  34. 62751 1:03 - 1:04
    and rotten eggs.
  35. 64216 1:04 - 1:07
    And a molecule known as Carbon Tetrachloride
  36. 66970 1:07 - 1:09
    which was used in fire extringuishers
  37. 69279 1:09 - 1:11
    and dry cleaning, until scientists
  38. 71190 1:11 - 1:13
    discovered it's highly toxic.
  39. 73000 1:13 - 1:15
    At this point, there's very little flesh left
  40. 75001 1:15 - 1:17
    and it's consumed by – here it comes –
  41. 77332 1:17 - 1:19
    maggots and beetles.
  42. 79032 1:19 - 1:23
    Insects leave only bones behind.
  43. 82571 1:23 - 1:26
    Over time, the protein in bone decomposes, too.
  44. 86306 1:26 - 1:28
    Leaving just the bone mineral called
  45. 88122 1:28 - 1:30
    Hydroxyapatite
  46. 89697 1:30 - 1:32
    which eventually turns to dust.
  47. 92476 1:32 - 1:34
    We can take some solace in the fact
  48. 94154 1:34 - 1:36
    that all those nutrients and chemicals,
  49. 96187 1:36 - 1:37
    even the dust,
  50. 97117 1:37 - 1:39
    provide vital substances that
  51. 98899 1:39 - 1:40
    make soils fertile,
  52. 100213 1:40 - 1:42
    sprouting plants and other new life
  53. 102107 1:42 - 1:44
    after our lives have ended.
  54. 105655 1:46 - 1:49
    Ashes to ashes, dust to dust.
