Or perhaps having the experience itself ("I survived the jump") is a significant contributor to their not regretting it. There could even be multiple mechanisms there: "turns out being that close to death is really scary," or "my survival means there is a higher power looking out for me," or "my life flashing before my eyes made me realize something about my life"...
