+    """Survival analysis was originally developed and applied heavily
+    by the actuarial and medical community. Its purpose was to answer
+    *why do events occur now versus later* under uncertainty (where
+    *events* might refer to deaths, disease remission,
+    etc.). *lifelines* is a pure Python implementation of the best
+    parts of survival analysis."""
