I think I saw a recommendation for suicide that the jump be at least eight stories.

“I think I saw a recommendation for suicide that the jump be at
least eight stories.”

That “death zone” phrase is one I heard tossed around by some friends
that were rock-climbers.
I’d guess the folks giving suicide advice are trying to assure “success”
by getting folks to jump from at at least 80 feet (not the 50 feet
of the rock-climber’s “death zone”).
