Where you jump when caution checks its email first.
means The most intense, difficult, or extreme part of something, especially thrown into without preparation or warm-up.
from Literal before figurative — swimming pools have a shallow end for waders and a deep end where the floor drops away and you actually have to swim. 'Jump/throw in at the deep end' emerged as a swimming-pool phrase, then dove into general English in the early-to-mid 1900s to mean facing the hardest version of a challenge straight off, no shallow-end practice allowed.
