  1. Death sucks!
  2. But what happens to your body
    after you die is fascinating.
  3. So we're going to show you.
  4. Don't worry, it won't be gross...much.
  5. Once a person's breathing stops,
  6. the cells in their body
    stop receiving oxygen,
  7. but the cells continue to live
    for several minutes
  8. generating carbon dioxide.
  9. Carbon dioxide is acidic,
  10. and it builds up,
    rupturing sacs inside the cells.
  11. These sacs contain enzymes
  12. that begin to digest the cells
    from the inside out.
  13. This creates a blister-like fluid
    rich in nutrients.
  14. After about a week, those nutrients
  15. fuel an army of bacteria and fungi
  16. that further liquefy organs and muscles.
  17. The microbes that attack the tissue
  18. produce a bewildering array of
    more than 400 chemicals and gases.
  19. They include freon.
  20. That's right, the coolant found in refrigerators.
  21. Benzene, a powerful component in gasoline.
  22. Sulfur, which smells
    of swamps and rotten eggs.
  23. And the molecule known
    as Carbon Tetrachloride,
  24. which was used in fire extinguishers
    and dry cleaning
  25. until scientists discovered
    it's highly toxic.
  26. At this point,
    there's very little flesh left,
  27. and it's consumed by... here it comes...
  28. maggots and beetles.
  29. Insects leave only bones behind.
  30. Over time, the protein
    in bone decomposes too,
  31. leaving just the bone mineral
    called hydroxyapatite,
  32. which eventually turns to dust.
  33. We can take some solace in the fact
  34. that all those nutrients and chemicals,
    even the dust,
  35. provide vital substances
    that make soils fertile,
  36. sprouting plants and other new life
  37. after our lives have ended.
  38. Ashes to ashes, dust to dust.
