20 years ago, I fell 20 feet at 15mph on my mountain bike, landing on my head and right wrist. My helmet absorbed much of the impact, as did my wrist. I was unconscious for about 5 minutes (according to the friends I was with), and had crushed the end of the radius, chipped the ulna, and cracked the navicular. There was no apparent damage from hitting my head (although some would argue otherwise). To this day, I'll swear that I never hit the ground, because I don't remember it happening. I was looking at the ground as I fell, but must have blacked out just before impact. I believe it was my brain's way of protecting my psyche, that it decided that I didn't need to experience the impact.
So my question is this: With regards to the guy who fell from the 27th floor, what do you think went through his mind as he fell, and did he in fact die before he hit the ground? A friend of mine thinks the guy may have stroked out before he actually impacted. What are your thoughts?
one at a time:

"Oops."

If it takes 5 seconds to impact, is it fair to guess the heart attack was induced about 2 seconds in? Three seconds left. In terms of brain death, we're talking about the amount of time it takes for the brain to be deprived of oxygen. I'm guessing it takes more than 3 seconds.

I think what's happening is this. At t-minus-2 you fall, brain processing normally, firing neurons as you flail about in vain attempt to steady yourself. T-minus-1, same. At t0 you hit. At t1, memory creation shuts down due to trauma and short term memory (containing memory data just before impact) is wiped out. In other words, I wouldn't say that your brain switched off during the fall, but rather erased stuff during the fall afterwards (or, if it didn't erase it, it's the trauma itself that prevented retention of the memories). Or something like that.
