67. When you die your hair still grows for a couple of months.
Technically that's not true.
Your hair stops growing (along with everything else) at the moment of death.
What actually happens is that the hair in the follicles are exposed due to tissue dessication that follows death. In other words, your moisture-laden skin (where the follicles dwell and incubate your luxurious hair) loses water during the decay/dessication process. Follicles shrink with the thinning, drying skin, but hair doesn't. So eventually only the root bulb of your hair remains within a shrunken follicle. That's why your hair appears so much longer a couple of months after you die. Oh, and your head overall shrinks a little too.
This process can take up to a couple of months, depending on the environmental conditions. If you die in the desert, for example, this will take but a week or so. But if you die in the Amazon Basin, then it will take a couple of months or even longer. Likely your skin/hair/body will mold and succumb to fungal infestation before it "grows" that long.
The same process happens with fingernails.
