Longevity as a distribution
Models thousands of lifespans—not a single "age 95"—so longevity risk is built in.
Sequence‑of‑returns risk & fat tails
Incorporates sequence-of-returns risks and large market drops into every simulation.
Health & LTC shocks
Includes stochastic health‑cost shocks to show how surprise bills affect chance of success.
Adaptive guardrails
Use adaptive withdrawal rules (e.g. Guyton-Klinger) that adjust as markets move.
