It's crazy because I was thinking yesterday, when I saw you write LEVEL 7, about crazy stuff like this:
Have two walls: one wall behind the athlete and one wall 100m of the athlete ahead. Also walls to the side, so the athlete is running in a cubicle. Now the walls in front and back can raise and lower to block the athlete. Have one hungry/angry bear released 100m behind him. Both walls hit the ground and block whoever is in between them as soon as either the bear or the athlete cross their respective finish lines (for the bear it's the athletes starting line, for the athlete it's a line 100m ahead of that).
So basically, if the athlete finishes first he'll be OK because he'll have two walls in between him and the bear. If the bear finishes first, then the athlete will be trapped in between the two walls with the bear inside that space as well.

I was thinking about this because my sister said to me when we were in the mountains that she thought once you see a bear you should run... so I saw LEVEL 7, I thought about all this ^^^ and now I dreamed what I wrote above.
Crazy shit and correlations happening in the brain. Maybe that stupid center (basketball player) was the bear? Whatever.
